It's tough being a teenage alien, even if you do have a pretty girl by your side.

By now, you've seen the "I Am Number Four" trailer, which showed us that being a visitor from another planet involves engaging in dangerous high-speed chases with shadowy forces that want you dead.  It also sometimes involves shooting balls of energy out of your hands that causes dudes to slam into trees.

And then there are its gorgeous stars, Alex Pettyfer and "Glee"'s Dianna Agron. 

If the trailer left you exhilarated but wanting more (and you simply don't have the time to run to the store and pick up the book), you'll want to check out "Number Four Origins," a behind-the-scenes look at the movie that gives a few more hints as to what exactly is going on in-between all the running and leaping about. 

Pettyfer and director D.J. Caruso give more details on their sci-fi thriller as well as a look at scenes that weren't included in the trailer.  They don't give away too much, though -- just enough to leave you wanting even more.  Clever movie people, they are!

"I Am Number Four" opens Feb. 18, 2011.
