5. Kyle Gallner
If you look up Kyle Gallner on IMDB, you'll see that he has only starred in one of the movies he's "known for" and it was an independent movie. And, SPOILER ALERT, he died in all of them! Well, I don't know if he died in A Haunting in Connecticut because I've never actually been able to get through that movie (not because it's scary, but because there just never seems to be anything that sets it apart from other paranormal movies, whatever - not the point!), but he may as well have. Gallner is a very sympathetic actor - I always feel for him when I see him on screen. It isn't the character - there have been characters that I'm meant to feel sorry for, but don't because of the actor/actress they chose to play them. Gallner is at that age when they can keep him looking young or they can style him to look a little older. Either way, he'll be able to handle it. He's the nice guy - they guy that sits in the back and watches everyone else get the better roles (never to be heard from again) while he remains the ever supportive cast member. He is ready for more, I can see it, so give him more, Hollywood!
