I Am Number Four star Dianna Agron has a day job a few pop culture fans may have heard of -- the monster hit Glee. Eager to not replay the same character as her career starts to sizzle, she found a different sort of high school girl in her character for the big screen adaptation of I Am Number Four.

In I Am Number Four, Dianna Agron portrays Sarah, a teen more interested in the art of photography than dating popular kids. Sarah has a deeper soul than Quinn, her Glee character, and Agron talked to us exclusively about why her role in I Am Number Four was a must for her career.

Agron's Sarah is smitten with the new boy in town, the mysterious John Smith (Alex Pettyfer). He is not like the other boys in her small town. For that matter, John is unlike anybody on earth!

I Am Number Four, based on the book of the same title, follows the story of John, also known as Number Four. He and eight other kids were jettisoned off their planet when it was invaded and completely destroyed by a mysterious and powerful army. As the film begins, Number One, Two and Three are all executed, which means Number Four is next as they can only be killed in order. And thus, our thrilling story begins.
