Event Horizon is a 1997 British-American science fiction horror film directed by Paul W. S. Anderson. The screenplay was written by Philip Eisner, with an uncredited rewrite by Andrew Kevin Walker. The film stars Laurence Fishburne and Sam Neill.
Set in 2047, the film follows a crew of astronauts sent on a rescue mission after a missing space ship, the Event Horizon, spontaneously appears in orbit around Neptune. Searching the ship for signs of life, the rescue crew learns that the Event Horizon was responsible for testing an experimental engine that opened a rift in the space time continuum, allowing a hostile entity on board the ship.
The film had a troubled production history, with filming and editing rushed by Paramount when it became clear that Titanic would not meet its projected release date. The original 130-minute cut of the film was heavily edited by demand of the studio, to the consternation of director Paul W.S. Anderson. Upon release, the film was a commercial and critical failure, grossing $26.7 million against a $60 million production budget; critics compared the film unfavorably to Alien, Hellraiser, The Black Hole, Solaris, Stargate, Fantastic Voyage, The Andromeda Strain, The Shining, and 2001: A Space Odyssey.
Despite its failure at the box office, the film began to sell well on home video; its initial DVD release sold so well that Paramount contacted Anderson shortly after its release to begin working on a restoration of the deleted footage. However, it turned out that the footage had either been lost or destroyed. In the years since, the film has slowly built a dedicated cult following and is often referenced and parodied in other works of pop culture.
