Yes, there may in fact be an "Arrested Development" movie. Here's Bateman on it:
I like Filmdrunk's rationale for why the movie should happen:
Arrested Development is probably the best show of all time, and since everyone on it (Bateman, Michael Cera, Will Arnett) is kind of a big deal now – except David Cross, who must have a thousand-dollar-a-day coke habit to be taking part in the Alvin and the Chipmunks movie – a movie would make sense.
Thanks for the mention, homes.
