One of the biggest sitcom stars ever — a TV legend who helped make Thursday nights "Must-See TV" on NBC — may be headed back to the network with a new sitcom.

Writing on Deadline.com, our good friend Nellie Andreeva reports in an exclusive story that Bill Cosby, 76, has made a deal with NBC to develop and star in a new half-hour comedy.

"In 1984, ‘The Cosby Show’ revived the sitcom genre and fueled NBC‘s ratings resurgence," Andreeva writes. "Three decades later, Bill Cosby is looking to bring some of that magic back to NBC, which has been going though a rough time with comedies. The network has made a deal for a half-hour family comedy to star Cosby."

Cosby has reportedly gotten back together with his old "Cosby Show" partner, producer Tom Werner, for the new project.

"The new comedy will be built around Cosby, who will play the patriarch of a multi-generational family and, like the comedian’s previous family sitcoms — ‘Cosby Show’ and ‘Cosby’ on CBS — will channel his take on marriage and parenting. Cosby and Werner are meeting with writers on the project, which has been put on off-season development track," Andreeva writes.

Cosby and Werner have reportedly been working for some time on the idea of a family comedy with wide appeal.

In November, Cosby told Yahoo TV: “They would like to see a married couple that acts like they love each other, warts and all, children who respect the parenting, and the comedy of people who make mistakes. Warmth and forgiveness. So I hope to get that opportunity, and I will deliver the best of Cosby.”

Cosby also reportedly has a remake in the works of his animated series "Fat Albert and the Cosby Kids."
