The biggest thing for me is I don't want to let people down. At the same time I love things that scare me and challenge me. If your job doesn't do that and doesn't excite you there's no point in doing it.

I Am Number Four is an action-packed adventure entwined with a romantic story. I play the role of John Smith. John wants to be a normal kid, but he is from a different planet and he has been given this destiny of becoming a warrior.

Pfft, who wants to make a movie about a guy in a house?

What I really love, is finding a script and fantasizing and going to a different world and kind of portraying a character that is interesting. Because other lives interest us, that's why we read magazines like People and try and fascinate and drool over what other people are doing.

When you play a character it's the persona you bring across from a book to film, or book to script to film. If I play Frank Sinatra, there's gonna be things I do in a movie that Frank might not have done, but it's the personality that comes across.

I think your emotion changes from person to person. As you get older, a lot of people become cynical because of the experiences they have had and haven't been able to let go of, whether they've been cheated on or whether it hasn't worked out. It's so easy to turn around right now and say, "Just let it go."
