Jeffrey Tambor: (on doing voice acting) You do a pass, then you do another pass, then you do another pass and then you do another pass. And then you start correcting it. It's very fast work, which I like, and it's very intuitive work. You work very mano a mano with the director, he has a very specific idea, which I love.
Jeffrey Tambor: (on doing voice acting) This is my first full length feature, but I've done a lot of cartoons, Hanna-Barbara and things like that. I like it. I used to do radio and things like that. I love it.
Jeffrey Tambor: (on Arrested Development) I play sort of a smaller cog in this, although a bigger cog this year. But it's an amazing group of people. I hope we do really well, people actually watch us this time which would be fun.
Jeffrey Tambor: (on the second season of Arrested Development) I'm back twice. I play my own brother, so I'm back with double vision. My apologies. I'm really excited and the word we're getting is we raised the bar even again.
