Chisel-jawed astronaut Chuck Baker (voiced by Dwayne Johnson) lands on what he thinks is an uninhabited planet, only to find it populated by little green men, in this fun animated adventure from director Jorge Blanco and Shrek co-writer Joe Stillman. What's more, this alien world bears a striking resemblance to 1950s America and its attendant fashions, fears and morals. With the help of some well-meaning alien teens, fish-out-of-water Chuck has to find his way back to his spaceship before it returns to Earth without him. The laughs come thick and fast in a sprightly kid-pleaser full of slapstick set-pieces and memorable characters, while more grown-up viewers will find themselves grinning at pastiches of the Cold War paranoia of bygone sci-fi movies, and good-natured digs at the era's emerging protest movement.

When Earth astronaut Capt. Chuck Baker arrives on Planet 51 -- a world reminiscent of American suburbia circa 1950 -- he tries to avoid capture, recover his spaceship and make it home safely, all with the help of an empathetic little green being.
