It's usually easy to predict which movies will become movies, like the Harry Potter series. Other times, it's a little confounding (Juno?!), and I'm surprised but pleased to learn of the new Wizard of Oz game for the Nintendo DS.
The 3D role-playing game is based on the book and the subsequent movie, and though it seems like a bit precious, it actually looks pretty cool.
So since you guys were so good at identifying which video games became movies, I want to bend your brains some more by getting your input.
If you could see any movie turned into a video game (that hasn't yet, natch), what would it be? Twilight? Bruno? The Hangover?
