Kiefer Sutherland is Jack Bauer sounds like Matt Damon is Jason Bourne. 24 is a great show. I compliment it, and I love every minute of it. The actors were great, the plot was outstanding. It wouldn't be that without Kiefer Sutherland. He is a great actor, he really is my favorite actor.
As for his other movies, he wasn't very important in them, but he deserved a better appearance. Shohreh Aghdashloo starred in The Excorcism(don't know how to spell it) of Emily Rose. That was a well deserved appearance, although I'm not sure if Shohreh starred there altough the character looked like her. But Kiefer is the best, and will remain my fave actor.
