SACHA BARON COHEN

AGE 33
WHO IS HE?
The star of HBO's hit Da Ali G Show, he's Ali G, the U.K.'s dimmest rapper.

THE DISGUISES: Ali G wears tracksuits, skullcaps, goggle-like shades and lots of bling; Baron Cohen also portrays Borat, a hopelessly unhip Kazakhstani journalist; and Bruno, a flamboyant fashion commentator from Austria. The real Baron Cohen is a British comedian who grew up in a close-nit Jewish family—his screensaver is a photo of his grandmother—and is a graduate of Cambridge.

HIS APPEAL: "When we're filming and a kid comes over, he gives him mementos from the wardrobe department, like a piece of clothing or a chain. He does a lot for charities," says the show's costume designer Jason Alper. Adds HBO programming executive Nancy Geller: "He's smart, good-looking and has a great tush."

TIM DELAUGHTER

AGE:39
WHO IS HE?
Lead singer of the 24-member Polyphonic Spree, known for groovy harmonies. Their second CD, Together We're Heavy, came out last summer, but appearing at the MTV Video Music Awards really raised their profile.

THE COSTUME: A colorful robe. "I figured by the time the crowd summed us up by what we were wearing they'd miss the music," says the father of three.

HIS APPEAL: "To be around Tim," says his partner, Julie, "is always to look at the bright side."

SETH MACFARLANE

AGE:31
WHO IS HE?
The creator of the animated series Family Guy and the voice for the demented baby Stewie, dad Peter and dog Brian. Canceled in '02, the show's impressive DVD sales led FOX to revive it for 2005.

ALTER EGO: Facets of MacFarlane appear in Peter, Stewie and especially the dog: "We're both liberal, enjoy a good Scotch and tend to get in awkward situations with women."

HIS APPEAL: "He sings like Sinatra," says a pal, "and has the social conscience of Gandhi."

GERARD BUTLER

AGE: 35
WHO IS HE?
The lead in Phantom of the Opera, due at Christmas, which promises to make him a superstar.

THE MASK: A piece of leather covering a "deformity" that took four hours of makeup to create. "As soon as I put on that mask I became somebody else," he says. "I also learned a lot of finesse in using a cape!"

HIS APPEAL: The Scottish actor (and former barrister) has a great sense of humor. "When I'm 80 and I'm sagging all over, I can tell my grandkids, 'Look, when I was a lad, PEOPLE magazine thought I was sexy!' " Says Phantom director Joel Schumacher: "He looks like a god in magazines, but when you're with him, he's a sweet, gentle and goofy guy."
