Biografia

Was roommates with Robert Downey Jr. for three years during their early days in Hollywood in the 1980s.

When his character, Jack Bauer, got a new tattoo (part of the plotline) for Season 3 of 24 (2001) instead of having to go though tedious make up for each scene which the tattoo would show, Kiefer had a real tattoo inked onto his arm.

During the fourth season of 24 (2001), he filmed a Public Service Announcement to tell viewers that the series' creators were not trying to exploit 9/11 in their storylines, and that the whole terrorist storyline was fictional.

Upon the conclusion of Season 5 of 24 (2001), Kiefer has spent more on-screen time as the character Jack Bauer than as all of his previous roles combined. He has also received more nominations for the series than his entire film career.

Has spent 15 hours a day, six days a week, for the last five years on the set of 24 (2001).

(his reaction to winning the Golden Globe Award!) Now I know how Charlie Sheen feels, I've lost all feeling in my lower half.

When you're a young actor you like to go for characters with a bit of flair, so in many films I ended up playing the weirdos. But I can assure you I'm not a psycho or a criminal or a bully.

There are two kinds of event in rodeo and bull riding's one of the roughstock events. I was into immobilising cows myself.

On his 1990s career: You could say I was not on everybody's first list to do the bigger films. Luckily, other opportunities have come along.

(on the much-hyped broken engagement to Julia Roberts) You can't do all these interviews about how wonderful you both are and then when it falls apart six days before your wedding not expect people to have a shot at you. I know Julia and I unwittingly asked for it.
