ET was first on the red carpet with Kiefer Sutherland today as he made a star appearance at Comic-Con to talk about his new big-screen thriller 'Mirrors.' We also chatted with him about season seven of "24," and Kiefer even took questions about his courageous 48 days in jail.

In our all-new candid interview, Kiefer also reveals his fears. The man who plays the FBI agent who saves the world on TV every week admits scary movies are enough to terrify him. Chances are, he may have a hard time sitting through his new fright fest 'Mirrors,' in which he stars as a troubled ex-cop plagued by evil forces who use mirrors to get back to their homeland. Kiefer is even afraid of mirrors.

"They freaked me out before [doing the movie]," he says. "I actually don't have very many mirrors. I actually have one mirror in the house and it's in my bathroom."

The highly anticipated, 'Mirrors,' hits theaters August 15.
