Interview with Sean Ohlenkamp, Co-Creator of "Oh My Gourd - A Halloween Stop Motion Pumpkin Carving Experiment"

Just in time for Halloween, stop motion animator Sean Ohlenkamp and photographer Robert Popkin have teamed up to bring us their spellbinding stop motion pumpkin carving experiment, Oh My Gourd, a special treat of a short film, many years in the making.

Two astonishingly talented animators, one stage – a wooden box with “character,” one black curtain, one all-pumpkin-themed soundtrack, several candles, and “dozens upon dozens upon dozens of pumpkins,” says Ohlenkamp, “cut, gutted, rotated, scraped, poked, slapped, and banged” were what it took “to make this stop-motion animation and the music that brings it to life.”

The film, a 2-minute romp through beautiful and extravagant pumpkin-themed stop motion effects, was made using several techniques that are not unknown to stop motion, effects that allow the medium to flourish and step out to be as creative and inventive as only stop motion can be. Casting aside the atypical Halloween iconography, Ohlenkamp and Popkin dive deeper, playing around with unique shapes and effects rarely implemented in stop motion – a rotating cube, a piano playing itself, and, of course, a buffering browser. To make the effects, Ohlenkamp explains, “Many pumpkins were photographed twice. First as a nicely lit, carving-free plate. Then again after carving our designs and removing the top or back so we could insert a light. The two were then composited together to remove the lighting equipment. We re-used pumpkins where we could (fronts and backs and sometimes sides) but that wasn’t always possible. We often projected images onto the pumpkins to help with the carving and to improve consistency between frames, but due to each pumpkin’s unique curves, it often took just putting it in front of the camera to check alignment.”


The music for the film, created by the eclectic sound design engineers at Grayson Matthews, was made, as Ohlenkamp says, “through what we’ve deemed ‘Pumpkin Orchestration.’ Grayson Matthews’ Igor Correia created this catchy rhythmically-driven underscore with the help of Tom Westin and the team of sound designers at Grayson….Most of these sounds were smashed, tapped, kicked, clapped or scooped out of actual pumpkins and carving tools, with some enhancement and sound manipulation courtesy of Logic and Protools.”

This film is not Ohlenkamp’s first rendezvous with stop motion, having worked with the medium before in his brilliant little Kellogg’s Rice Kirspies commercials and for his short film, The Joy of Books.

For Ohlenkamp and Popkin, Oh My Gourd was a labor of love. As Ohlenkamp states, “It took a few years – pumpkins rot, schedules get busy – but we loved discovering the methods that worked and the many that didn’t.”


The video has begun to go viral since its release four days ago, now clocking almost 44,000 hits.

“We hope this inspires others and can’t wait to see what you create!” Says Ohlenkamp.

I had recently had the pleasure to interview Sean and to mull over the minute wonders of his film. Enjoy!

A.H. Uriah: Can you give us a little walk-through of the production of Oh My Gourd, from first concept final product?

Sean Ohlenkamp: We were initially hoping to make it a narrative. But neither of us are professional carvers (if there is such a thing!) and it proved far too difficult to align the detailed animations needed to carve frames of a character. So we simplified it down to the looping sequences of shapes and movement you see here. It was designed partially out of necessity and partially out of the want to do something that didn't lean into all of the more expected Halloween imagery of carved smiles and witches and bats. For each frame we shot two photos. One where we nicely lit the exterior, uncarved pumpkin. And one where we cut the back, top, or side off the pumpkin, gutted it, carved it, and lit it from the inside. We then merged the two images back together to make sure both the pumpkin and the carving looked good. Without doing so would have resulted in the pumpkins turning into bright red glowing orbs because of the strobe we placed inside!


A.H. Uriah: You mention in the description of Oh My Gourd that there were “many animations that didn't make it into the final piece which seemed like good ideas at the time but ended up being too complicated and did not work (a carved heart that emerged and beat with the pulsing of the light, a complex Halloween themed pumpkin zoetrope, and an animation of a tree that grows as the pumpkins sizes do among others).” How did you decide which pumpkin designs to use in the final video and how did you go about creating the final effect that we see in the film?

SO: Honestly it became which animations were the clearest. The more complex ones ran into issues when the frames did not align clearly enough. Essentially, you couldn't tell what was happening. There was a lot of trial and error throughout the process. The clearest bits of animations seemed to be short loops which set a bit of a pattern for the eye to follow which could make up for our poor carving skills.


A.H. Uriah: In the production of Oh My Gourd, you worked closely with the incredibly talented photographer Robert Popkin during the production of the video, as well as with the composer Igor Correia and a team of sound designers in the musical composition for the project. What did your collaborations look like in the process of making “Oh My Gourd?" Do you have a particular approach to collaboration and particular methods for communicating with your creative collaborations?

SO: It was a wonderful collaboration with Rob Popkin and the team at Grayson Matthews. Rob was the photographer and we developed the concept together. We both bought carloads of pumpkins, stored, carried them, and gutted them. I ended up doing most of the carving while Rob was behind the lens. Once we had the assets, we started compiling them to see what worked and didn't, creating a rough edit. We supplied that to Grayson Matthews (who also composed the music for this other stop-motion piece of mine) with the suggestion that the music also feel part of the space and use pumpkins where possible. They took that to heart and came back with a beautiful score using both pumpkins and the tools used to carve them. We then refined both the edit and the music together to make things line up and create a bit of a resolution to these otherwise random carving experiments. It was a great collaboration with both of us feeding off one another.



A.H. Uriah: It would appear as if you faced several challenges along the way while making this project. The ones you’ve noted are working with natural objects (pumpkins) and, as such, you were forced to work under the constraints that they put you under; another challenge being the limitations of working with pumpkins, and having to come to terms with the fact that some of your ideas were simply too elaborate to work practically. I’m sure you faced more challenges, as well, that I’m not aware of. Although from coming out of this project having worked under the constraints and conventions of the project, do you have any advice for stop motion filmmakers who might be facing similar challenges on their own projects? What did you yourself learn from the challenges you faced on this production and what answers did you devise to remedy these challenges?

SO: In terms of advice, I don't know that I'm in a position to give it! I just create things to satisfy personal curiosity and meet self-imposed challenges. But commitment and passion will lead to great things!

(Note on below picture: Sean mentions that, “The scissors/cuts one was a test pumpkin that I thought looked pretty cool. We were going to have scissors cut along a dotted line to open the pumpkin at the end but it didn't really work out.”)

"Robot Jox"

With the upcoming RoboCop remake I though it only necessary to discuss the 1989 action flick Robot Jox. Robot Jox was the first massive project for David Allen Productions, and to watch the movie shows you that with $10,000,000 and a devoted and passionate crew, you can accomplish a magnificent final product.

Robot Jox, full film: http://youtu.be/jZXWHswqCQo



According to Ray Harryhausen, the gigantic Stop Motion puppets were, "The robot puppets for Robot Jox were so heavy that they often needed to be supported by tungsten wire sliding along overhead rails while walking."


Even though the critics were none to pleased by this film, many new and unseen things were accomplished in this film.  It is worth a look or two.




I hope after reading this post and watching the film you will agree with me, even though it's not Shakespeare, this is a innovative, and interesting masterpiece of film.

Interview with Mark Smith, Director and Writer of Stop Motion Short Film, "Two Balloons"

As I sit, listening to Peter Broderick’s moving composition for piano More Of A Composition, I close my eyes and envisage an enormous funnel cloud skimming across the crystalline face of an ocean – the skies are murky and unusually dark, lightning crackles, spider-webbing across the darkened skies before then vanishing, and still, after its gone, an electricity continues to hum in the air and I simply know that it’s going to soon strike again. And as the scene presents itself to me, I suddenly feel something similar to what director Mark C. Smith felt when he saw the same image as he sailed to a small island called Grenada along with his wife in a timeworn sailboat. For him, in that moment inspiration struck, and the idea suddenly came to him for his heartfelt stop motion film, Two Balloons. For me, I open my eyes and feel as I did the instant Two Balloons faded to black – as if I’ve just woken from a stunning and beautiful dream, one I immediately mourn not being able to see again f…

Interview with Kangmin Kim, Director of Stop Motion Short Film, "Deer Flower"

The experience of childhood is something like existing within a waking dream. In childhood, as in particularly vibrant dreams, the distinct and unique experience presents itself to simply exist in each moment without explanation or reflection – to become fully and wholly enveloped in each and every moment, the option of operating outside of which is somehow nonexistent. In that special time in one’s life, moments simply are. And yet, childhood, like dreams, is a fragile and temporary reality. It’s not until one “wakes” from childhood, by entering adulthood, that one can reflect upon and appreciate the past and, in retrospect, realize just how odd and unusual certain experiences might have actually been. Korean filmmaker and animator Kangmin Kim captures this feeling beautifully in his outstanding short film Deer Flower.

Deer Flower tells the semi-autobiographical of auteur Kangmin Kim’s childhood experience of dealing with persistent illness and of taking one of the remedies his paren…

Interview with Niki Lindroth von Bahr, Director, Writer, and Animator of Stop Motion Short Film "Bath House"

In art as in life, when in the thick of something – a chain of, at times, loosely connected actions and consequences – it can be easy to miss “the point.” It’s often only in retrospect – the moment when one can contemplate, assessing and reassessing an event, whether mundane or abnormal – when one can discover meaning and a “point” to events in life as in art. When in the thick of something, things often feel commonplace, moments of actual weight sporadic, chaotic, and adrift, lost in the moment.

Niki Lindroth von Bahr’s Bath House – a 15-minutes-long short film – perfectly captures these feelings of disorder and inconsequential consequence in the midst of the mundane and seemingly aimless. This mood is further accentuated in the film by a disquieting lack of a soundtrack, using dialogue only sparingly which perfectly accompanies Bahr’s incredibly lifelike puppets and animation, together harmonizing and bringing to life moments and an atmosphere that are rarely (if ever) captured on …

Interview with Joseph Wallace, Director of Spark's "Edith Piaf (Said It Better Than Me)" Official Music Video

Neon feathers fly and a midnight chase ensues in a 1930s’ Paris imagined by BAFTA Cymru nominated director Joseph Wallace, traversing through streets, caf├ęs, and across rooftops sporting tilted chimneys and scaly shingles in the music video for legendary American pop-alternative band Sparks’ latest hit, “Edith Piaf (Said It Better Than Me),” praised by the band as, “Perhaps Sparks’ best video ever.”


The video is a gorgeous and somewhat psychedelic romp through the stylized 1930s’ Paris cityscape – “Piaf’s Paris,” as dubbed by Wallace – through which we follow stop motion versions of the Mael brothers, Ron and Russell, whom together comprise Sparks, as they follow a large, neon-colored bird – a sight that provides a stark contrast to the otherwise moody, muddy color palette of Wallace’s Paris, composing a beautiful and exciting ambiance of 3-and-a-half-plus minutes of pure cinematic bliss.

The world of the film was built primarily using cardboard, the backgrounds were painted panorama…

Aardman Co-Founder David Sproxton's Tips for Success in the Animation Industry, Part 2 (of 3): 4 Production Tips

Over the course of Aardman co-founder David Sproxton’s two in-depth interviews with Watershed’s Mark Cosgrove, it becomes blatantly obvious that his easy-to-listen-to, soft-spoken words offer an invaluable resource to animators and filmmakers alike in the way becoming successful in the business of animation.

In keeping with the theme of last-week’s article, this week signifies the second post in Stop Motion Geek’s series of articles on advice for animators and filmmakers accrued from Sproxton’s interviews with Cosgrove about the history of Aardman, wittily titled “Aardocs.” Last week, the elements of Sproxton’s advice that I chose to write about primarily pertained to pre-production, whereas this week I’ve chosen advice of his that pertain primarily to the process of production. His advice – posted below – span everything from importance of knowing your limitations to an excellent way to to build your skill-set as an animator or filmmaker to the value of creative and technical constr…

"Welcome To My Daydream" Documentary About Stop Motion Filmmaker Will Vinton Now on Kickstarter

With four days left to go on Kickstarter, the documentary about the Oscar-winning filmmaker and Claymation filmmaker, Will Vinton, Welcome To My Daydream, climbs steadily towards its goal of $35,000 with 10k left to raise.

Will Vinton, one of the stop motion industry’s most undervalued pioneers – who, in 1978, coined and trademarked the term “Claymation” – was the founder of Will Vinton studios, under which he contributed to creating iconic Claymation characters such as the California Raisins, ‘80s Domino’s mascot Noid, the non-Claymation Red and Yellow M&M’s, as well as having spearheaded Claymation films such as The Adventures of Mark Twain and A Claymation Christmas Celebration, as well as dozens of other feature-length and short films.

Welcome To My Daydream tells the little-known saga of Will Vinton’s career and the and rise and fall of Will Vinton Studios, a stop motion production company founded with high hopes only to eventually fizzle out in the early 2000s, bereft of fund…

Behind the Scenes of "Robocop 2" at Tippett Studios and how "Jurassic Park" Changed Special Effects Forever

A depressingly large percentage of Hollywood movies boast a gratuitous amount of potential and possibility and yet, for one reason or another, often fall far, far too short to live up to the films they seem to have the potential of being. Although it’s a shame that many of these films have a stupendous level of production value and talent but are often often overlooked, as production value and talent are seen as secondary and supplementary to a quality story – the special effects work done on such second-rate films sadly go unrecognized the most often. An immutable fact stands strong – mediocre films, no matter the level of talent and amount of time poured into producing their special effects, are seen and remembered as nothing but wasted potential…or worse. Yet few box office bombs have had special practical effects work as groundbreaking, especially in the stop motion realm, and yet unfortunately remains unrecognized in every respect than the 1990 film Robocop 2, both an irrefutabl…

Aardman Co-Founder David Sproxton's Tips for Success in the Animation Industry, Part 1 (of 3): 3 Pre-Production Tips

“It all started at a kitchen table,” says co-founder of Aardman Animations, David Sproxton, about the beginning of his career in animation, “Pete [Peter Lord] and I met as schoolkids….Pete and I got to be great mates and we started playing and thinking up stories. I was always interested in photography and kind of, I guess, the process thing about films….One day we got out the Bolex, stuck it up on a stand and actually just cut images out of color supplements. We’d obviously watched programs like Vision On, which obviously used a plethora of styles. Cut out is the easiest thing to do. We didn’t really understand cel animation or actually how you drew stuff. We just moved stuff around and did stuff with chalk drawings.”

Earlier this year, Aardman, in celebration of the 40th anniversary of their studio, released a conversation with David Sproxton that follows-up an earlier interview with Watershed’s Mark Cosgrove that was released in 2010. These mini-documentaries – cheekily dubbed “Aa…
