Natalie Portman is one of the biggest stars in Hollywood, able to do everything from psychological drama to outrageous R-rated comedy. But back in 1994, she was just a little girl, albeit a little girl to be reckoned with. Luc Besson's 1994 film The Professional (originally released as Leon in France) was Portman's screen debut; she immediately earned her cred playing a 12-year-old who teams up with a veteran killer (Jean Reno) when her family is killed by corrupt cops. Hilarious and frighteningly precocious, Portman set the stage for the likes of Hit Girl in last year's Kick-Ass; those who caught this film back then just knew she was going to grow up to be awesome. And she did. —Zack Smith
