5. Dane DeHaan
I think after Chronicle, DeHaan stood out to a lot of people. It's really a nice breath of fresh air when completely unknown actors hit the big screen in a big way and impress a lot of people. I was excited to see him in Lawless, working alongside Shia LaBeouf and Tom Hardy. If I were in DeHann's shoes I would've lost my mind in excitement. All that aside, he's a very talented actor who is capable of creating a believable and genuine performance. He's young and looks like a spoiled rich kid on the verge of breaking. That's exactly what Harry Osborn is supposed to look like. Out of anyone on this list, DeHaan looks the most like a potential Green Goblin. That's an important component to consider when casting the role. If they're feeling risky they can even give him that weird striped red and black hair, but we'll probably just settle for something darker than the blonde he sports now.
