According to Variety, "Arrested Development" thesp Will Arnett has been cast in Red Wagon's "RV" at Columbia, joining leads Robin Williams and Cheryl Hines. Barry Sonnenfeld is directing the pic, which begins shooting this month in Vancouver.

Arnett will play Todd, slave-driving boss to Bob (Williams) at the Sparkle Beverage Co., who tells Bob that if he wants to keep his job he can't go on vacation but instead has to take a meeting in Colorado. Bob opts to load his family into an RV en route to Boulder, hoping they won't realize the real reason for the trip.

On the feature front, Arnett has been on a tear lately. He'll next be seen in New Line's Monster-in-Law, starring Jane Fonda and Jennifer Lopez, and was just cast as the lead in Paramount's "Dad Can't Lose," to be directed by Joe and Anthony Russo.

Arnett and the Russos are also attached to an untitled comedy project written by Chuck Martin that was sold last month to Universal.
