Which actor played Jack Bauer in the TV series 24?

Kiefer Sutherland played Jack Bauer in the television series 24.

Sutherland portrayed Bauer, an American counter-terrorism agent, throughout the original series and its later revival. Bauer works for the fictional Counter Terrorist Unit, commonly called CTU, and is repeatedly drawn into plots involving terrorism, assassination attempts, biological threats, nuclear weapons, and political conspiracies.

The series premiered on Fox on 6 November 2001. Its distinctive format presents each season as 24 consecutive hours, using real-time storytelling, split screens, and an onscreen clock to heighten the pressure. Sutherland’s performance made Bauer one of television’s best-known action protagonists and earned him both a Primetime Emmy Award and a Golden Globe Award.

The original run lasted from 2001 to 2010, followed by the limited revival 24: Live Another Day in 2014. Sutherland is sometimes confused with the actors who played Bauer’s colleagues: Carlos Bernard played Tony Almeida, Dennis Haysbert played David Palmer, and William Devane played James Heller.
