When sitcoms get big screen spin-offs, the results are typically rather dreadful. Will Mitch Hurwitz’s Arrested Development cheat this curse? It will have to make it into production first.

This movie has been threatening to get rolling for quite some time. On again, off again rumours have been trickling forth from interviews with the cast for at least a couple of years. And yet still, and not for all the love in the world, has the darn thing actually gone before cameras.

The latest updates come from GQ, who were spurred on by affirmative comments from Will Arnett to call up Mitch Hurwitz themselves and have him give backup. Both star and writer pretty much promised that the film is all but inevitable:

[W]e were talking to Will Arnett. And this is what he said: “Yes, it’s happening.” He went on, but here’s the upshot: there is a script—!!!—but it is not finished; all of the principle cast members are on board, but there is no timetable to actually make the movie. So then we called Mitch Hurwitz to make sure that our ears did not deceive us and that Arnett wasn’t just pulling our leg. They didn’t, and he wasn’t.

“Believe it or not, we have started the script,” Hurwitz told GQ. (And by “we,” he means himself and “Arrested” co-executive producer Jim Vallely.) “We’re taking a little abeyance while we get ['Running Wilde'] up and running. But it is our absolute next priority and we can’t wait to do it.”

Believe it or not? Yeah, I’ll believe you’ve started it. Dare I believe you’ll ever finish it? I’m fearing that 100 pages of script might prove just as hard to line up as the popular and in-demand cast.
