Chuck Baker (Dwayne Johnson) arrives on Planet 51 -- a world reminiscent of American suburbia, circa 1950 -- he discovers that its inhabitants have long feared invasion from "aliens" such as himself. With the help of a sympathetic youngster, Chuck must elude capture and find a way back home. Jorge Blanco directs this animated thrill ride that also features the vocal talents of Jessica Biel and Gary Oldman."
