By Gregg Goldstein

NEW YORK (Hollywood Reporter) - Dwayne "The Rock" Johnson and Jessica Biel will voice lead characters in the computer-animated sci-fi film "Planet 51."

The film revolves around a group of residents on the eponymous planet who fear an alien invasion. Johnson will play astronaut Capt. Charles "Chuck" Baker, who arrives from Earth and confirms their worst fears. He's forced to avoid capture so he can find his spaceship and return home.

Biel will voice the film's female protagonist and the love interest of a local, voiced by Justin Long, who befriends Chuck. Seann William Scott will play another local.

The project is set up at New Line Cinema, and marks the studio's first animated feature in its 40-year history.
