Will funnyman Bob Newhart ever do another TV series? It's sad to think George &#038 Leo — his failed 1997 sitcom co-starring Judd Hirsch — was his last hurrah on the small screen.

"I think that's it," Newhart sighs. "It's a different time. It's a different generation. A lot of the subjects that were sacred cows when I started out in 1960 no longer are. I think there's confusion now, with gross passing for humor. They aren't the same thing."

These days, Newhart prefers dabbling in the movies. You'll recognize him as Sid the doorman in Legally Blonde 2: Red, White & Blonde (opening Wednesday). Besides a fine script, he says the appeal of star Reese Witherspoon drew him to the role. "I'd seen Reese in Election," he recalls, "and I thought she was incredible, for someone that young to be that good. It was a chance to work with Reese that came out of the blue."

He was less fond of other co-stars on the set — particularly his canine castmates. In Blonde 2, Elle Woods's devoted dog, Bruiser, finds a love match. "One of the dogs had a gas problem," Newhart laments, "and that caused certain expressions on my face that weren't acting. I don't know if that part made it into the movie."
