NBC has added three comedy projects to its slate for next season, untitled half-hours from Harris Wittels & Ali Rushfield and Dan Mazer (Borat) and Gifted from David Bickel (Kickin’ It). The untitled Harris Wittels project, from Universal TV and 3 Arts, is a family comedy about a well-meaning slacker who lives with his parents and is in a constant struggle with his family about how best to raise his younger brother, a multimillionaire high school entrepreneur. Wittels is writing with Rushfield supervising. The two executive produce with 3 Arts’ Dave Becky, Tom Lassally and Josh Lieberman. Wittels, who is under an overall deal at Uni TV, is repped by 3 Arts, CAA and Attorney Jared Levine; Rushfield, who also is writing a put pilot mother-daughter comedy for Fox,  is repped at UTA.

The Dan Mazer multi-camera project, from 20th TV, Tom Werner’s Good Humor TV and 3 Arts, is described as an adult relationship comedy. CAA-repped Mazer is writing and will exec produce with Werner and Lassally. Werner operates as an independent producer this season after a long tenure at Warner Bros. TV.

The multi-camera comedy Gifted, from Uni TV and studio-based producer David Janollari, is described as “Family Ties meets Big Bang Theory in a family setting.” It features two average, middle-class parents who find themselves out of their element raising an intellectually gifted teenage son. The project stems from the pod deal Janollari inked with Uni TV earlier this summer. Bickel is with Gersh.
