Will Arnett Will Arnett

Even though Will Arnett stars in one NBC comedy and will take part in the recently announced Arrested Development reunion, that's not stopping him from setting his sights on taking down Jack Donaghy.

Arnett will return to 30 Rock as gay shark and Jack's nemesis, Devon Banks, TVGuide.com has learned.

A date for Arnett's return has not yet been set, but the Arrested alum previously told us he'd love to see Banks get back on top after becoming a house husband with a gaggle of children.

30 Rock returns midseason, while Up All Night airs Wednesdays at 8/7c on NBC.
