Will Arnett and David Cross

It's an Arrested Development reunion! David Cross has just inked a deal to team up with former AD costar Will Arnett and creator Mitch Hurwitz in the new fall series Running Wilde, a Fox rep tells TV Guide Magazine.

Cross will appear in seven of the first 13 episodes, including the pilot (airing Tuesday, September 21 at 9:30/8:30c), and he will play Andy, the radical environmentalist fiancé of Keri Russell's Emmy who has been living with her in the Amazon. Cross takes over the role from Andrew Daly, who played Andy in the show's original pilot.

Are you excited to see Cross and Arnett together again?
