Get ready for some A-list aliens. 

Sarah Jessica Parker, Jessica Alba, Brendan Fraser, Rob Corddry, James Gandolfini and Craig Robinson have signed on to voice characters in the family-friendly Escape from Planet Earth. 

The Weinstein Company and Rainmaker Entertainment announced the voice cast for their tale of an alien breakout from Area 51 Tuesday.

Fraser will play the film's hero Scorch Supernova, who, along with his brother Gary (Corddry) must go to Earth to save trapped aliens.  Parker voices Kira, Gary's wife, while Alba will portray the no-nonsense Lena and Gandolfini serves as the film's bad guy, Shanker. 

The film, which is currently in production, is helmed by Cal Brunker (Despicable Me) and set for a 2012 release.

"A successful animated movie starts with an imaginative story and appealing characters," Catherine Winder, president and executive producer at Rainmaker Entertainment, said in a statement. "The addition of such high caliber voice talent is a crucial layer to the mix.  With the amazing array of talented artists and creatives from both The Weinstein Company and Rainmaker collaborating on this production, we have all the right ingredients to make Escape from Planet Earth a highly entertaining and successful film."
