George Clooney
He's not a doctor, he just played one on TV. But oh how we wished he were one. When ER debuted in 1994, gorgeous George's Doug Ross had us all redefining the term "bedside manner."
Johnny Depp
Long before he made a career out of playing quirky characters, Depp wasn't nearly as deep during his days as Officer Hanson on the late-'80s cop show 21 Jump Street. But then again, that's not exactly why we tuned in either. Sorry, Booker.
Will Smith
Saving the world from an alien invasion is definitely hot. But it doesn't hurt when the person taking on that responsibility in 1996's Independence Day also revealed his newly bulked-up beautiful self. No wonder Will quickly went from being the Prince of Bel-Air to the King of the Box Office.
Julia Roberts
The hair! The smile! That infectious laugh! Maybe the 1990 box-office hit should have been called Perfect Woman. You know, if you ignore the whole hooker thing.
Cameron Diaz
Much like Jim Carrey's character in 1994's The Mask, moviegoers found themselves picking their tongues off the floor as the onetime model made her acting debut. Yep, there's just something about Cameron.
Gerard Butler
You know it's saying a lot when one can be surrounded by 299 other studly Spartans, like those in 2006's 300, and still stand out from the crowd.
Tom Cruise
This Hollywood heartthrob may have proved he had all the right moves when he danced in his skivvies in 1983's Risky Business, but it was his role as flyboy Maverick three years later in Top Gun that allowed Cruise to capitalize on his greatest asset. Two words: Killer. Grin.
