Planet 51

Planet 51


Planet 51 is an animated movie that opens with scenes of the idealistic suburban life led by green aliens on Planet 51. This is a world curiously similar to 1950s America in terms of styles and attitudes. Clothing, vehicles, household appliances and architecture all reflect the fashions of the mid-20th century, as does the aliens' fear of outsiders.

One afternoon, Planet 51's peaceful existence is interrupted by the arrival of human astronaut Captain Charles Baker (voice of Dwayne Johnson). He had believed that the planet was uninhabited. After their initial shock, the locals react with hostility, calling in military strongman General Grawl (Gary Oldman) and his taskforce to deal with the situation. Meanwhile, Captain Baker meets a conservative teenager, Lem (Justin Long), who eventually promises to help the astronaut return to his spaceship and escape.

Other characters are Lem's younger brother Eckle (Freddie Benedict), Neera (Jessica Biel), whom Lem would like to date if he had the courage, guitar-playing protester Glar (Alan Marriot), and mad scientist Professor Kipple (John Cleese).

  • Flying plates knock over alien soldiers.
  • Alien soldiers punch each other in the face.
  • An adult alien gets his fingers caught in a car and is dragged down the street.
  • The astronaut smashes two aliens' heads together.
  • Several alien soldiers chase and fire weapons at the astronaut and the teen aliens assisting him.
  • Alien soldiers begin shooting each other. They are then electrocuted and left smouldering on the floor.
  • An entire army base is destroyed by explosives, apparently killing dozens of alien soldiers.
  • A mad scientist tries to carry out brain operations on the astronaut and any local traitors.

  • An alien mother threatens her young son by saying that if he doesn't take his medicine, a 'big, bad monster' will get him. Immediately following her words, the alien child sees the astronaut shoot past the window. This scares the child so much that he drinks the whole bottle of medicine.

  • A small, dog-like robot wees oil in fright after it is interrogated by army personnel.

Ideas to discuss with your children

Planet 51 appears to be aimed at children, but has an unusual combination of features. The movie contains several clever references to 1950s American pop culture and the political landscape of that era. In some ways, the plot could be seen as challenging idealised views about 1950s life, and asking questions about who the real aliens are, especially in the wake of 9/11. But these elements are not linked together in any coherent way. Several viewers might not even pick up the subtle references, which will be entirely lost on the targeted pre-teen audiences.

Values in this movie that you could reinforce with your children include accepting people who are different.
