Date: 1956

Vitals: William Shakespeare's The Tempest gets a sci-fi spin in this retro-futurist classic, as a team of explorers stumble across Altair IV — a colony world now deserted but for a brilliant scientist, his beautiful daughter and a dark secret. The film's best-known for introducing Robby the Robot to the world, but it actually holds up. ...

Famous Names: Walter Pidgeon, Anne Francis, Leslie Nielsen (Cast).

Crunchy Goodness: 4

Elevator Pitch: "You know what Shakespeare needs? Robots and space aliens!"
