What movie should I choose?

I am having a birthday party coming up soon and I am a teen...I want to have some friends over and I was planning on watching a movie with them. But, I am completely clueless on what movie we should watch..I was thinking Vampires Suck or Step Up 3D. But, I dont think those are coming up on DVD anytime soon. So, could you please give me some suggestions for recent movies for teens.

P.S: It cant be Percy Jackson and the Lightning Thief because we saw that at another bday party. Thanks Everyone!!!What movie should I choose?
