Billy Crystal is heading back to the small screen for a new comedy show.

The When Harry Met Sally... star made his name on Tv, landing his big break on sitcom Soap before becoming a Saturday Night Live regular in 1984.

He went on to carve out a successful movie career, but he will return to his roots in new scripted show The Comedians.

Crystal will play an ageing superstar stand-up who is forced to team up with a contemporary comedian for a late-night Tv show.

John Landgraf, president of FX Entertainment, says, "It truly is an honour to be in business with Billy Crystal and (writer) Larry Charles, two of the all-time greats in comedy. We're incredibly excited about this project."
