Sutherland vows to keep making 24

Kiefer Sutherland has vowed to keep making hit US TV show 24 until fans start switching off.

The actor, who plays Jack Bauer in the hit programme, has already wrapped five seasons and insists his appetite hasn't waned.

He says: "I would love to do it. But my concern is, how many bad days can one guy have. The audience will let us know when it's time to stop."
