Both, actually. Here's how the production process works: First things first, Trey writes the scripts -- usually a scene or two at a time -- and then that script gets sent around to all the different departments. Storyboard begins immediately to sketch out and board the scenes, while Trey and Matt jump into the recording booth to lay down the audio they just wrote. Next the audio and storyboards are combined in to a sort of motion comic called an animatic. Once the animatic is approved, the storyboards get passed out to the Technical Directors (who set up the shots) and animators (who start animating). It's a pretty amazing, well-oiled machine here. And it's all done in-house, in America. Fuck yeah!
