The Times Interviewing Jason Bateman seems to think so:
'A big-screen version of Arrested Development is planned for next year.'Jeffrey Tambor was promoting Hellboy 2 on Craig Ferguson and he also mentions doing it next year! Great interview but scroll to 7:15 if you wanna see him mention the movie!
“When it was on TV, if you missed one word the whole third act could be blown for you. And TV is a different experience. You come home and you've got to finish a call so you miss the first ten minutes or you get snacky and you go to the fridge and you miss another two minutes, so it's a different experience to film.”
