Brian Yuzna (born August 30, 1949) is a cult producer, director, and writer, known for "Honey, I Shrunk the Kids", "Bride of Re-Animator" and "Beyond Re-Animator" who has been active within the independent horror genre for over thirty years.
 He is widely known as the producer behind "Re-Animator", as well as being the first American filmmaker to adapt a manga into a live-action feature.
 He has helmed several adaptations of the work of H. P. Lovecraft, and has assisted many first time directors, including Stuart Gordon, Christophe Gans and Luis De La Madrid, in getting their projects made.
From Beyond is a 1986 American 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.
Edmond is a 2005 American drama film directed by Stuart Gordon and starring William H. Macy, based on the 1982 play "Edmond" by David Mamet.
 Mamet also wrote the screenplay for the film.
 "Edmond" features Julia Stiles, Rebecca Pidgeon, Denise Richards, Mena Suvari, Joe Mantegna, Bai Ling, Jeffrey Combs, Dylan Walsh and George Wendt in supporting roles.
 It was screened at several film festivals from September 2005 to May 2006, and had a limited release on July 14, 2006.
Robot Jox is a 1990 post-apocalyptic science fiction film directed by Stuart Gordon and starring Gary Graham, Anne-Marie Johnson, and Paul Koslo.
 The film was co-written by science fiction author Joe Haldeman.
 The film's plot follows Achilles, one of the "robot jox" who pilot giant machines that fight international battles to settle territorial disputes in a dystopian, post-apocalyptic world.
William A. Seiter (June 10, 1890 – July 26, 1964) was an American film director.
Robert Mapplethorpe ( ; November 4, 1946 – March 9, 1989) was an American photographer, known for his sensitive yet blunt treatment of controversial subject-matter in the large-scale, highly stylized black and white medium of photography.
 His work featured an array of subjects, including celebrity portraits, male and female nudes, self-portraits and still-life images of flowers.
 His most controversial work is that of the underground BDSM scene in the late 1960s and early 1970s of New York City.
 The homoeroticism of this work fuelled a national debate over the public funding of controversial artwork.
Stuart Gordon (born August 11, 1947) is an American filmmaker, theatre director, screenwriter, and playwright.
 Initially recognized for his provocative and frequently controversial work in experimental theatre, Gordon is perhaps more widely known for work in film.
 Most of Gordon's cinematic work is in the horror genre, though he has also ventured into science fiction and film noir.
 Like his friend and fellow filmmaker Brian Yuzna, Gordon is a fan of H. P. Lovecraft and has adapted several of the author's stories for the screen, including "Re-Animator", "From Beyond", and "Dagon", as well as the "Masters of Horror" episode "Dreams in the Witch-House".
Dolls is a 1987 Italian-American horror film directed by Stuart Gordon, produced by Charles Band and Brian Yuzna and was written by Ed Naha.
 It stars Stephen Lee, Guy Rolfe, Hilary Mason, Ian Patrick Williams and Bunty Bailey.
 In the film, during a harsh thunderstorm, a group of six people arrives at the mansion of an old puppetmaker and his wife.
 The film eventually reveals that the puppetmaker's puppets in the house are actually cursed immoral people who had been killed and imprisoned in puppet bodies for years in order to pay for their crimes.
Stuck is a 2007 thriller film directed by Stuart Gordon and starring Mena Suvari and Stephen Rea, with a plot inspired by a true story.
 The film premiered on May 21, 2007 at the Cannes Film Market.
 It was later adapted in Bollywood as "Accident on Hill Road" starring Celina Jaitley in Mena Suvari's role.
Re-Animator, also known as H. P. Lovecraft's Re-Animator, is a 1985 American science-fiction horror comedy film loosely based on the H. P. Lovecraft episodic novella "Herbert West–Reanimator".
 Directed by Stuart Gordon and produced by Brian Yuzna, the film stars Jeffrey Combs as Herbert West, a scientist who invents a solution which can re-animate deceased bodies.
 He and Dan Cain (Bruce Abbott) begin to test the serum on dead human bodies, and conflict with Dr. Carl Hill (David Gale), who is infatuated with Cain's fiancée (Barbara Crampton) and wants to claim the invention as his own.
