EXCLUSIVE: NBC has bought half-hour comedies from writer-actress Stephnie Weir and sitcom veteran Peter Murrieta. Coincidentally, the two were at Chicago’s Second City together.

Weir’s Leisure Club, from Sony Pictures TV and studio-based Original Films, has received a script commitment with a sizable penalty from the network. It revolves around a group of younger Baby Boomers living in a 55+ retirement community who revert back to the archetypes they were in high school. Weir will executive produce with Original’s Neil Moritz and Vivian Cannon. Weir’s manager Meghan Schumacher will also produce. The project stems from the last of several blind script deals Weir had at Sony TV. The previous two resulted in two comedy pilot orders at ABC, for the Debra Messing starrer Wright vs. Wrong in 2010 and Counter Culture this past season. Weir is with UTA and attorney David Fox.

Murrieta’s comedy is a multi-generational family show based on his own family – juxtaposing the immigrant generation, the assimilation generation and the modern one. This is an area Murrieta first mined in his maiden series as a creator, the WB’s Greetings From Tucson. He is executive producing the NBC project with 3 Arts. CAA-repped Murrieta served as showrunner on the first three seasons of Disney Channel’s Wizards Of Waverly Place showrunner, helping  the comedy achieve ratings success and land the first best series Emmy Award for the network.
