Animated comedy adventure featuring the voices of Gary Oldman, Jessica Biel and John Cleese. When American astronaut Captain Charles ‘Chuck’ Baker (voice of Dwayne Johnson) lands on Planet 51, he thinks he is the first person ever to set foot on it. To his surprise, however, he finds that the planet is inhabited by small green people who live contentedly in a white picket fence world reminiscent of 1950s America - and whose only fear is that it might be overrun by alien invaders… such as Chuck. Chuck must now do all he can to escape becoming a permanent exhibit in the Planet 51 Alien Invaders Space Museum.
