Carol Leifer sets up at CBS, Showtime

'Seinfeld' scribe teams with Marlee Matlin, Mario Cantone

Carol Leifer got her writing break on "Seinfeld" with the "Lip Reader" episode, her first produced script.

Now she has reteamed with Marlee Matlin, who guest starred on that episode, and actor-comedian Mario Cantone for a single-camera comedy at Showtime.

The Fox TV Studios-produced project, which would star Matlin and Cantone, is one of two half-hour projects that writer-comedian Leifer has in the works.

At CBS, she has received a script order for a multicamera comedy produced by Sony Pictures TV and Happy Madison.

Inspired in part by Leifer's real-life situation of being in a long-term, same-sex relationship and having a child with her partner, the CBS show, tentatively titled "You and Me and He," centers on a recently divorced woman who enters a gay relationship only to find out that she is pregnant with her ex-husband's baby.

"I'm excited about it because it's really hard in the multicamera format that has been on TV for so long to do something new and different and to push the envelope to a certain degree," Leifer said.

The sale of the project coincides with a resurgence of the multicamera genre, which is enjoying strong interest from the broadcast networks this development season.

Leifer has strong multicamera roots, going back to "Seinfeld" and CBS' "The Ellen Show," which she created.

She most recently worked on another multicamera comedy, CBS' "Rules of Engagement," also produced by Happy Madison and Sony. That led to her partnering with the companies for the new project, which garnered interest from several networks before landing at CBS.

The Showtime comedy, "Mouthpiece," is set at a high-powered law firm.

Matlin, with whom Leifer had stayed in touch since the 1993 "Lip Reader" episode, approached the writer with the idea that she and Cantone had come up with.

Leifer, who has known Cantone since their early stand-up days at the Improv, quickly jumped on board.

"I love the synchronicity of it -- we all have worked together," Leifer said.

Matlin is a familiar face at Showtime, where she recently co-starred on "The L Word."

Leifer, who recently published her first book, the best-selling compilation of humorous essays "When You Lie About Your Age, the Terrorists Win," is repped by CAA.
