Kiefer William Frederick Dempsey George Rufus Sutherland is a Canadian actor and musician. He is best known for his starring role as Jack Bauer in the Fox drama series 24, for which he won an Emmy Award, a Golden Globe Award, two Screen Actors Guild Awards, and two Satellite Awards.

Jack Bauer is a fictional character and the protagonist of the Fox television series 24. His character has worked in various capacities on the show, often as a federal agent of the Counter Terrorist Unit (CTU) based in Los Angeles, and working with the FBI in Washington, D.C. during season 7. Within the 24 storyline, Bauer is a key member of the CTU, its Director in Season 1, and is often portrayed as their most capable agent. Bauer's job usually involves helping prevent major terrorist attacks on the United States, saving both civilian lives and government administrations. On many occasions, Jack does so at great personal expense, as those he thwarts subsequently target him and his loved ones. He is not a crooked agent; however, Bauer's frequent use of torture to gather information has generated much controversy and discussion.
