Jason Bateman thinks it is too late for an 'Arrested Development' movie.

The actor - who played central character Michael Bluth in the hit US sitcom for three seasons until February 2006 - admits he doesn't think people are still going to be interested in a spin-off film.

He said: "Perhaps that ship has sailed."

Despite his reservations, the 'Up In The Air' star admitted work is well underway on the project.He added to MTV News: "Mitch Hurwitz, the creator just had a very busy television season. Now that that has finished, he's intensely writing the movie. My guess is he's halfway done with it. My guess is we'd be shooting it in eight, nine, 10 months and then it would be out six or seven months later."
