The television star will be taking off her cheerleader outfit and putting on probably another cheerleader outfit to play a high schooler in the sci-fi flick.

Teresa Palmer has joined the already booming cast of the D.J. Caruso directed science fiction thriller I Am Number Four. The film tells the story of nine aliens who escape their home planet just before it’s blown to bits by a rival species, only to come to Earth and disguise themselves as human high schoolers.

According to the Heat Vision, Sharlto Copley (District 9, The A-Team) is in talks to co-star in Dreamworks’ I Am Number Four.
