The hotly-anticipated Arrested Development movie is suffering delays because Will Arnett is working on a new show with writer Mitchell Hurwitz.

Fans of the hit TV comedy are awaiting news of the upcoming big screen version, scheduled for release next year. And funnyman Arnett has assured supporters the movie is still going ahead - but he and Hurwitz are also penning a brand new comedy together.

He tells the New York Daily News, "The Arrested Development movie is definitely going to happen. But Mitch and I have been working on the new show, so unfortunately for the movie, we have been focusing on that for the last couple of months."

A representative for Arnett adds, "They are working on the movie simultaneously."
