At this point, there is exactly one good reason for an "Arrested Development" movie: So that the people involved with "Arrested Development" no longer have to answer questions about an "Arrested Development" movie.
In an interview with GQ, Will Arnett, Mitch Hurwitz and Jim Vallely had to take time off from promoting their upcoming FOX comedy "Running Wilde" to swear that an "Arrested Development" movie will happen. Someday. Maybe. Although the author of the GQ article gets all excited -- three exclamation points -- that "there is a script," that's not actually what anybody in the article says. Hurwitz says that they've *started* a script, which isn't the same thing, since he's been saying that for more than a year-and-a-half.
The "Running Wilde" team had to give an update to counteract David Cross' previous statements that the "Arrested Development" movie was dead, which some publications took seriously, as David Cross would be the one person to know this. And the GQ story treats it as some huge exclusive break that Hurwitz and Arnett say the exact same thing they've said for two years.
"Believe it or not," Hurwitz tells the magazine, "I do not enjoy teasing our wonderful and devoted audience, which is one reason it appears that I've been so cagey about this. It's just that I don't want to promise what I can't deliver."
So there you go. The "Arrested Development" movie isn't dead. It's just waiting for a script, production, shooting and editing.
