Today, we celebrate the birthday of Justin Long, who turns 33 today. After getting his big-screen start in the 1999 film Galaxy Quest, Long continued to grab roles in a string of comedic films. I personally believe he's more effective as a supporting character, but he has shown the ability to maintain a movie's lead position. He has a dorky persona that translates well to the silver screen, and he's played some off-beat characters in the past. Even when he's in some not-so-great movies, he tends to be the one to elicit some of the laughs. So here's my five favorite Justin Long roles - I hope you enjoy them. Once again, happy birthday Justin Long!
