You can actually improvise a lot as a voice actor. It's not that entirely different than shooting a live action movie; the characters mouths are quite easy to manipulate once all the information is built into the computer. So you can improvise a lot and it doesn't matter really how far along they are in the process they can really just make the character say something different.
Seth RogenI watch a lot of TV. I love nothing more than having a good TV show on DVD, to just plow through.
Seth RogenWe were really fortunate to work [on Pineapple Express] with a studio that was really supportive of these guys. It was before Superbad and Knocked Up had even come out, but everyone just felt really great about them and the energy surrounding Seth [Rogen] and Evan [Goldberg] and Judd [Apatow] - all of these guys - and the idea of getting Franco back into comedy as well.
