Shaun Cassidy (“The Agency”) has sealed a two-year overall deal with Warner Bros. TV to produce and develop primetime skeins.

As part of that deal, Cassidy has been named executive producer on the upcoming CBS crime drama “Cold Case.”

Cassidy will remain exclusive to “Cold Case” in the show’s first year and may remain with the show for year two and/or develop new projects for the 2004-05 season.

“Cold Case” stars Kathryn Morris as a Philadelphia homicide detective who’s assigned to long-unsolved crimes, referred to as “cold cases.” Eye drama airs Sundays at 8 p.m. this fall. Show comes from Warner Bros. TV, Bruckheimer Prods. and CBS Prods. Besides Cassidy, Jerry Bruckheimer, Jonathan Littman and Meredith Stiehm exec produce.

“Shaun’s got a great sensibility, he really gets the show, he loved it,” said Littman, who runs Bruckheimer’s TV operations. “We love that passion. We want someone who gets what you’re doing and will enjoy working on the show.”

Cassidy, who’s repped by CAA, most recently spent two years on “The Agency,” serving as exec producer and showrunner. He also created and exec produced the USA drama “Cover Me,” created the NBC skein “Players” and exec produced Fox’s “Roar.”

The former thesp and singer first made a name for himself as a scribe in 1995, when he created the critically acclaimed CBS drama “American Gothic.”

Littman said he was thrilled to bring Cassidy on board in time for the start of production on “Cold Case.” “These types of procedurals are enormous shows to launch,” he said. “There’s so much to do from production to post-production.”
