Jim Carrey

The youngest of four children born to Percy (an accountant and aspiring jazz saxophonist) and Kathleen, Jim Carrey was an incurable extrovert from day one. As a child he performed constantly, for anyone who would watch, and even mailed his résumé to "The

Carrey's transformation from TV goofball to marquee headliner happened within the course of a single year. He opened 1994 with a starring turn in Ace Ventura: Pet Detective (1994), a film that cashed in on his extremely physical brand of humor (the character's trademark was talking out his derrière).
Next up was the manic superhero movie The Mask (1994), which had audiences wondering just how far Carrey's features could stretch.

Finally, in December, he hit theaters as a loveable dolt in the Farrelly brothers' Dumb & Dumber (1994) (his first multi-million dollar payday). Now a box-office staple, Carrey brought his manic antics onto the set of Batman Forever (1995), replacing Robin Williams as The Riddler.

He also filmed the follow-up to his breakthrough, Ace Ventura: When Nature Calls (1995), and inked a deal with Sony to star in The Cable Guy (1996) (replacing Chris Farley) for a cool $20 million--at the time, that was the biggest up-front sum that had been offered to any comic actor.

The movie turned out to be a disappointment, both critically and financially, but Carrey bounced back the next year with the energetic hit Liar Liar (1997). Worried that his comic shtick would soon wear thin, Carrey decided to change course. In 1998, he traded in the megabucks and silly grins to star in Peter Weir's The Truman Show (1998). Playing a naive salesman who discovers that his entire life is the subject of a TV show, Carrey demonstrated an uncharacteristic sincerity that took moviegoers by surprise.

He won a Golden Globe for the performance, and fans anticipated an Oscar nomination as well--when it didn't materialize, Carrey lashed out at Academy members for their narrow-minded selection process. Perhaps inspired by the snub, Carrey threw himself into his next role with abandon. After edging out a handful of other hopefuls (including Edward Norton) to play eccentric funnyman Andy Kaufman in Man on the Moon (1999), Carrey disappeared into the role, living as Kaufman -- and his blustery alter-ego Tony Clifton -- for months (Carrey even owned Kaufman's bongo drums, which he'd used during his audition for director Milos Forman). His sometimes uncanny impersonation was rewarded with another Golden Globe, but once again the Academy kept quiet.

An indignant Carrey next reprised his bankable mania for the Farrelly brothers in Me, Myself & Irene (2000), playing a state trooper whose Jekyll and Hyde personalities both fall in love with the same woman (Renée Zellweger).

Carrey's real-life persona wound up falling for her too--a few months after the film wrapped, the pair announced they were officially a couple. By then, Carrey had already slipped into a furry green suit to play the stingy antihero of Ron Howard's How the Grinch Stole Christmas (2000).

He plans to take a break from the limelight after the holiday flick (as he puts it, "I'm looking forward to getting out of America's face"). Is there another Carrey reinvention in the works? If so, he's not talking.
