A new full trailer has arrived for animated flick Planet 51, courtesy of Yahoo. Check it out below:

The story follows intrepid astronaut Chuck Baker (voiced by Dwayne “The Rock” Johnson) as he launches into space, on a mission to explore a new planet. On landing, however, he discovers the planet looks exactly like Earth and his current surroundings like a ’50s-era suburban America. Other than the indigenous population being green, they’re… just like us! When a crusading alien general sets it upon himself to stop the “invasion,” Baker must rely on the help of a local alien teen (Justin Long) to get back to his orbiting command module that is scheduled to return to Earth in 3 days, with or without him. Jessica Biel, Seann William Scott, Gary Oldman, and John Cleese are also in the voice cast. Planet 51 hits theaters November 20, 2009.
