Equinox is a 1970 American supernatural horror film directed by Jack Woods, and starring Edward Connell, Barbara Hewitt, Frank Bonner and Robin Christopher.

The film focuses on four young people picnicking in a California canyon, where they stumble upon an ancient book used to conjure demons; soon they unleash a plethora of evil creatures.

[4] The film was originally conceived as a short by producer-director Muren—then titled The Equinox: Journey into the Supernatural—who developed and shot it with friends Dave Allen and Jim Danforth in 1967.

The cult film[5] has been influential to the horror and sci-fi monster genres, receiving praise from filmmaker George Lucas and special effects artist Ray Harryhausen.

The reporter listens to tape recordings of the police interviewing David soon after he was brought to the hospital and reconstructs the events — told in flashback — that drove him insane.

David, Susan Turner, Jim Hudson and his girlfriend, Vicki, search for Dr. Watermann in a forest canyon and find that his cabin has been destroyed.

The book, which Watermann's notes describe as a "veritable bible of evil", reeks of sulfur and contains the Lord's Prayer written backwards.

After killing Vicki, Asmodeus attacks the now-awake David and Susan, who flee to a cemetery and cower behind a large stone cross atop a grave.

While studying business at Pasadena City College, producer and aspiring filmmaker Dennis Muren devised a short science fiction film, The Equinox ... A Journey into the Supernatural, with his friends Dave Allen and Jim Danforth.

[2] Re-titled to simply Equinox, Muren was credited as associate producer in spite of having directed much of the film and creating the special effects himself.

[14] In his review of the film, Bill Gibron from DVD Talk wrote, "In a strange way, Equinox is The Evil Dead with Ray Harryhausen substituting for Sam Raimi.

Club rated the film a grade B, writing, "It's clear these guys had more ingenuity than resources, and watching Equinox is like a lesson in how to make something out of nothing.

[20] In an article for the Criterion Collection, Brock DeShane quotes Tom Sullivan, special effects and makeup artist for the Evil Dead movies, about seeing the film.
