It Came from Outer Space is a 1953 American science fiction horror film, the first in the 3D process from Universal-International. It was produced by William Alland and directed by Jack Arnold. The film stars Richard Carlson and Barbara Rush, and features Charles Drake, Joe Sawyer, and Russell Johnson. The script is based on Ray Bradbury's original film treatment "The Meteor" and not, as sometimes claimed, a published short story.

It Came from Outer Space tells the story of an amateur astronomer and his fiancée who are stargazing in the desert when a large fiery object crashes to Earth. At the crash site, he discovers a round alien spaceship just before it is completely buried by a landslide. When he tells the local sheriff and newspaper editor what he saw, he is branded a crackpot. Before long, odd things begin to happen, and the disbelief turns hostile.
