NBC has bought Grow The F**k Up, from writer Ali Rushfield, while CBS has put in development How To Grow Up, from scribes Evan Susser and Van Robichaux.

NBC’s Grow The F**k Up, produced by Universal Television, centers on a 36-year-old woman with arrested development who has a relationship with the only person who gets her — a 20-year-old college student. Jesse Peretz (Girls, New Girl) is set to direct the project, which is executive produced by feature producer Anthony Bregman (Friends With Money) through his Likely Story production banner, Rushfield and Peretz. Rushfield, repped by UTA and attorney Bryan Wolf, is a co-executive producer on NBC’s Parks And Recreation and is writing a feature for Sony and Matt Tolmach based on her original idea. Peretz, repped by UTA and Brillstein, previously wrote, executive produced and directed the feature Our Idiot Brother, which was produced by Bregman, repped by ICM Partners.

CBSHow To Grow Up, from ABC Studios, centers on a 30-year-old lawyer who reconnects with his inner child when he discovers a box of VHS taped messages he recorded when he was 10 years old; each recording contains pointed advice for his future self on how to not grow up to be a “stupid, boring adult.” Comedy veterans Jeff and Jackie Filgo executive produce with writers Susser and Robichaux, who are alumni of the Upright Citizens Brigade Theatre in LA. The duo’s feature script Chewie was ranked No. 3 on the 2011 Black List, and they are currently writing a live-action version of The Jetsons for Warner Bros. Susser and Robichaux are repped by WME, Industry Entertainment and attorney Jeffrey Frankel.
