Talkback Thames is reportedly developing a new Saturday night gameshow for BBC One.

According to Broadcast, the show will be based around the concept of time, with Chris Evans a possible choice to present.

Called The Clock Is Ticking, the magazine says the show features contestants sitting in a room, unable to see the time, with them having to guess how much time is left when they re-emerge. They have the chance of winning a cash prize, and with the opportunity to play for a grand prize of £75,000.

The production company, which makes ITV1 show PokerFace, is believed to have showcased the idea to BBC commissioners last week.
