Accentuating the Positive [BR] As Will on the hit NBC sitcom Will and Grace, Eric McCormack has won many fans for his positive portrayal of a gay man. "I get a lot of letters from young gay men who consider Will a role model," says McCormack, 37. "I think he is: He's a fully out and proud gay man who at the same time functions in straight society and is very well-adjusted." The actor admits that he had to overcome a few reservations about the part. "I had fears," he says. "But hopefully now I am a role model for straight actors who were afraid to play gay." In fact, McCormack is ready and willing for the show to cast a boyfriend for his character. "But we have to find the right guy," he says, adding with a wink, "someone who will be hilarious and good-looking." [P] Wiz Kid [BR] Ten-year-old Liam Aiken, who plays Kim Basinger's son in the new drama I Dreamed of Africa, says that his big dream is to portray Harry Potter in the upcoming movie based on author J.K. Rowling's beloved boy wizard. "I've been chasing the role for a year," says Aiken, who plans on lobbying director Chris Columbus himself. "I'm going to be filming [LB]Sweet November[RB] soon in San Francisco and Chris lives there, so I hope we become best friends." As for his competition, Aiken says that two of the leading contenders, The Sixth Sense's Haley Joel Osment, 12, and Malcolm in the Middle's Frankie Muniz, 14, are, ahem, too old. "In the first book [LB]Harry Potter and the Sorcerer's Stone[RB] and in the movie, Potter is [LB]11[RB]," Aiken notes, "which means I'm the perfect age." [P] A Sure Betty [BR] "This is the first time I've been required to sit at home and watch cartoons in the name of research," says Ally McBeal's Jane Krakowski of her role as Betty Rubble in the new live-action flick The Flintstones in Viva Rock Vegas. After viewing the toon, the actress didn't want to be Wilma (played by Kristen Johnston). "If you're going to be one of the big four, I think Betty is the way to go," says Krakowski, 31. "She's a showgirl. She's sexy. She does end up with Barney, but Fred's no prize either." So who does she think her TV boss, Ally McBeal, would go for—Fred or Barney? "She'd have a tortured relationship with both of them," she says, "and, in a very Ally move, end up as the only single career woman in Bedrock." [P] Those Dancin' Feet [BR] Peter Gallagher, who plays a demanding artistic director in the ballet drama Center Stage, due May 12, says that his ninth-grade dance performance was a big career turning point. "My first dance teacher almost scarred me for life," says Gallagher, 44. "He directed me in You're a Good Man, Charlie Brown. Up until curtain he was trying to give me triple-time moves with these complicated crossovers. I was short-circuiting. Finally I said, 'I'm just gonna go out there and move so fast and smile so much that the audience will love me no matter what.' I brought down the house as a dancing Snoopy. It's been pretty good for me onstage ever since. I just keep moving fast and smile all the time." [P] For His Name's Sake [BR] After costarring with Dennis Quaid in the new suspense thriller Frequency, actor Jim Caviezel [The Thin Red Line) hopes that a few more folks will know how to pronounce his name. "I've been asked so many times, 'Caviezel, that's a difficult name to say. Have you ever thought of changing that? Why don't you?' " says Caviezel, 31, whose Swiss last name, for the record, rhymes with "a weasel." "And I say, 'Can you say Schwarzenegger? You learned how to say that, didn't you?' " [P]
