Will Arnett isn't putting all of his eggs in one comedy basket next season; EW reports that the "Up All Night" and "Arrested Development" star has been cast in the lead role of CBS' untitled Greg Garcia comedy pilot.

According to EW, Arnett will play a recent divorcé whose life becomes infinitely more complicated after his parents start having marital difficulties of their own. The pilot hails from "My Name is Earl" and "Raising Hope" creator Greg Garcia, with "Friends" director Jim Burrows set to film.

Arnett's role is still in second position to NBC's struggling "Up All Night," so if that series moves forward with its multicamera reboot, Arnett will have to bow out of the CBS project. Still, with Christina Applegate's exit after numerous behind-the-scenes changes, and Maya Rudolph's recently announced pregnancy, there's some doubt as to whether "Up All Night" will continue in its new format or simply be cancelled.
