The single-camera comedy from The Mindy Project's Charlie Grandy centers on one husband's desperate struggle to not let every weekend go completely to hell.

Riggle will star as Charlie Bishop, an energetic, overcommitted yet blindly confident father of three kids who is happily married. At work all week, Charlie relies on weekends to reconnect with his family and be the kind of "hands-on" father he didn't have growing up.

Curtin will play Louise, the wry and fun mom to Kelly who's currently living at — and smoking cigarettes in — Kelly's and Charlie's house with her husband, Doug. Forced to babysit, Louise has a more relaxed attitude toward child rearing than Kelly and Charlie, and has no problem leaving her three grandchildren alone while she and Doug walk to the Mini Mart.

Grandy will pen the script and exec produce the Universal Television and TBD Productions comedy alongside Peter Traugott and Rachel Kaplan.

Riggle's credits include NBC comedy pilot The Pro, Adult Swim's NTSF:SD:SUV, Drunk History and Modern Family as well as features 21 Jump Street and its sequel and Dumb and Dumber To. He's repped by WME, Principato-Young and Sloane Offer. He also was the subject of a proposed Modern Family spinoff.

For Curtin, the role marks her return to broadcast following runs on Unforgettable, Gary Unmarried, Crumbs, '80s comedy Kate & Allie as well as 3rd Rock From the Sun. She's repped by ICM Partners
