Will Smith turns 45 today! The actor was -- as you all know -- born in Philly on this day, September 25, in 1968. He went on to become the "Fresh Prince of Bel-Air" before blowing up as a bona fide movie star with "Independence Day" in 1996. He's known for his charm, his attitude and his way with a one-liner, but he's also proven he can drop the comic schtick and be serious when the role requires it.
Of course, like every big star, Will's had his share of box-office stumbles, including this year's "After Earth." Fortunately, he has plenty of great movie moments to balance it out. Below, we count down Will Smith's best and worst moments on the big screen.
