Genndy Tartakovsky on making Hotel Transylvania:
“I took all the aesthetics I like from 2-D and applied them here. I don’t want to do animation to mimic reality. I want to push reality. You want to have your own identity. You don’t want to have an expression that Pixar has. That was super important to me. In 2-D, the way you draw defines you, but in CG the computer takes away your identity. I wanted to make sure the movie had my point of view.”
There’s more surprisingly frank commentary from Genndy in this LA Times piece.
