Ruby (1977 film)

Ruby is a 1977 horror drama film directed by Curtis Harrington, which was one of his last horror films. The film centres on a woman named Ruby Claire played by Piper Laurie who is the mother of a deafmute girl. She runs a drivein theatre where bizarre things begin to happen to her employees and the spirit of her dead husband possesses her daughter.

Soon strange and bizarre accidents claim the lives of Rubys employees, then Leslie begins to show strange behaviour, and then begins to speak... in her dead fathers voice. Nicky Rocco possesses his daughters body and terrorizes Ruby with levitations, telekinesis, maniacal laughing and bizarre sexual aggression.Ruby was long available on video in the U.S. only in a butchered version that was reedited and apparently reshot by director Stephanie Rothman for television, deleting the Rrated violence and adding new dialogue scenes. ........
