From Beyond is a 1986 science-fiction body horror film directed by Stuart Gordon, loosely based on the short story of the same name by H. P. Lovecraft. It was written by Dennis Paoli, Gordon and Brian Yuzna, and stars Jeffrey Combs, Barbara Crampton, Ken Foree and Ted Sorel.

A group of scientists have developed the Resonator, a machine which allows whoever is within range to see beyond normal perceptible reality. But when the experiment succeeds, they are immediately attacked by terrible life forms.
