Portland Monthly Magazine just did a extensive 'making of' article on Laika's The BoxTrolls for their Fall Arts Preview. Sculptures, armatures, art, 3D printed faces, and sets, yes, this article has it all. I highly recommend this. I will say that this is a microcosm of a BoxTrolls making of book. So go do yourself a favor and go study this article!
Laika’s first two films, Coraline (2009) and ParaNorman (2012), each grossed more than $100 million and received an Oscar nomination for Best Animated Feature. The Boxtrolls, Laika’s third feature, hits screens nationwide September 26, with voices from the likes of Sir Ben Kingsley and Tracy Morgan. The film conjures the studio’s most imaginative realm yet: the decadent, Victorian village of Cheesebridge, where humans live aboveground and garbage-scavenging boxtrolls live below. The $50 million project is the result of 350 people shooting 125,280 individual poses over the course of 18 months.
