Question: I was watching 24 and I think one of the guys from that show was on a different show. I only watched two minutes because my TV went out so I don't know their names. Can you tell me if any of them are on a different show? Thanks. — Kristina, Louisville, Ky.

Televisionary: Y'know, Kristina, I used to work in a bookstore oh so many years ago and a week didn't go by without one customer or another wandering in with incredibly vague approaches, like: "I'm looking for a book with a yellow cover. It's about an unhappy kid and that's all I know — do you know that one?"

Matter of fact, the woman who came in with that question left happy even though I, in my pre-Televisionary days of altruism, was ready to blow her off because she couldn't give me anything more than that. My co-worker Dan, on the other hand, gave her a pleasant "just a minute, please," disappeared back into the store and returned with a yellow-covered paperback copy of

J.D. Salinger's classic The Catcher in the Rye. The woman left, all excited, whereupon I asked Dan how in the world he knew what she was talking about. "I didn't," he said. "But I knew that edition had a yellow cover. It's about an unhappy kid and she'll be very glad she read it." So to carry on Dan's grand tradition of giving in this holiday season, I'll answer your question, especially since it's easier than the example I just gave. Of the actors who play the two major characters on the show, Kiefer Sutherland and Dennis Haysbert, only one has been in a series, so I'll guess you're talking about him and hope beyond hope that it does the trick for you. Haysbert, who portrays imperiled Presidential candidate David Palmer, most recently appeared on the small screen on CBS's Now and Again. He played Dr. Theodore Morris, the semi-benevolent Frankenstein wannabe who saved subway victim Michael Wiseman (John Goodman)'s brain and sent him out to battle evil in the body of Eric Close. You may also have seen Haysbert in such big-screen offerings as Love &#038 Basketball or Love Field.
