Sideswiped by Swank
"I lived, slept, ate, breathed, drank boxing," says Hilary Swank, 30, of preparing to play a fighter in Million Dollar Baby. Swank's training regimen included a daily intake of 210 grams of protein and four hour workouts six days a week. "I'd wake myself up punching. I hit my husband [actor Chad Lowe] a couple of times." Lowe didn't mind taking a few punches when he was awake. "He sparred with me once in a while," she says. "I hit him a couple of times and he couldn't believe it. I was like, Yeah, watch it—there's more where that came from.'"

Carrey's Killer Instinct
Unlike his cruel, kid unfriendly Count Olaf in Lemony Snicket's A Series of Unfortunate Events, Jim Carrey would like to have more children in his life. "If I get in a [meaningful] relationship, absolutely," says Carrey, 42, who has a 17-year-old daughter, Jane, from a previous marriage. In fact he's pretty keen on babies. "I like the humans in any form. I like the new visitors. It's a great thing." Is his new movie too scary for kids to see? "I don't think we can really understand the psychological ramifications of this film yet," jokes Carrey. "Maybe 10 years from now, when this generation grows up, we'll see if an abnormal number of them become serial killers."

Anjelica's Angst
The famously mercurial Bill Murray may not be the most predictable actor to work with—which is why Anjelica Huston thinks he was a great costar. "He's sharp, mordant, ironic, insolent, melancholic and completely charming. I have a huge crush on him," says Huston, 53, who is married to sculptor Robert Graham. The actress, who appears with Murray in the quirky new comedy The Life Aquatic with Steve Zissou, was also impressed by the physical sacrifices her costar made. "It was particularly grueling for him because he was out at sea in December in a Speedo. For me the most grueling part of the process—and I know this sounds silly—was the endless hair extensions being re-glued to my head every day."

Minnie's Phantom Voice
Minnie Driver knows her musical limits. "To sing opera is not something that you can just pick up and do," says the actress, 34, explaining why she lip-synched her role as a diva in The Phantom of the Opera. "That full sound is a lifetime's training. I could sing Chicago or West Side Story, but approximating Mozart, Verdi and Wagner would have been arrogant. We all drive cars, but we're not all racecar drivers." Plus, she adds, "it's fun having somebody else's voice come out of your mouth."
