Dear Stacy: Tell me about the actor who plays Lex Luthor on “Smallville.” He is perfect in this role. — Keith S., Long Island, N.Y.

Dear Keith: He may be quite the villain on TV, but the actor himself, Michael Rosenbaum, is a charming guy with a quirky sense of humor.

The single 33-year-old grew up in Indiana and went on to graduate from Western Kentucky University with a theater arts degree. After graduation, he immediately moved to New York to become a professional actor.

Clearly it worked. In his free time, he is an avid hockey player and participates in many celebrity hockey events. He also has a passion for music, and plays both acoustic and electric guitar. He also had his very own karaoke system installed in his Los Angeles home.
