Question: Which of the following directed "House on Haunted Hill": John Schwert or William Malone?
Context: House on Haunted Hill is a 1999 American horror film directed by William Malone and starring Geoffrey Rush, Famke Janssen, Taye Diggs, Ali Larter, and Jeffrey Combs.  It also includes a cameo appearance by Peter Graves.  The plot follows a group of strangers who are invited to a party at an abandoned asylum, where they are offered $1 million each by an amusement park mogul if they are able to survive the night.  Produced by Robert Zemeckis and Joel Silver, it is a remake of the 1959 film of the same title directed by William Castle, and features special effects by famed make-up artists Gregory Nicotero and Dick Smith. Return to House on Haunted Hill is a 2007 direct-to-DVD horror film and the sequel to the 1999 film "House on Haunted Hill".  Directed by Víctor García and written by William Masa, the film stars Amanda Righetti, Tom Riley, Cerina Vincent and Erik Palladino.  The film follows Ariel Wolfe - younger sister of Sara Wolfe; the previous films protagonist - being forced by a group of people to search for a mysterious idol hidden inside a haunted psychiatric asylum. Supernova is a 2000 Swiss-American science fiction horror film written by David C. Wilson, William Malone and Daniel Chuba and directed by Walter Hill, credited as "Thomas Lee."  "Thomas Lee" was chosen as a directorial pseudonym for release, as the name Alan Smithee had become too well known as a badge of a film being disowned by its makers.  It was originally developed in 1988 by director William Malone as "Dead Star," with paintings by H. R. Giger and a plot that had been called ""Hellraiser" in outer space."  Jack Sholder was hired for substantial uncredited reshoots, and Francis Ford Coppola was brought in for editing purposes.  Various sources suggest that little of Hill's work remains in the theatrical cut of the film.  The film shares several plot similarities with the film "Event Horizon," released in 1997, and "Alien Cargo," released in 1999.  The cast featured James Spader, Angela Bassett, Robert Forster, Lou Diamond Phillips, Peter Facinelli, Robin Tunney, and Wilson Cruz.  This film was shot by cinematographer Lloyd Ahern and scored by composers David C. Williams and Burkhard Dallwitz. Parasomnia is an independent horror film directed by William Malone and stars Jeffrey Combs, Timothy Bottoms and Dylan Purcell.  The filming was funded by Malone himself, and its release was delayed due to difficulties securing distribution. John Schwert (born November 20, 1975) is a film and commercial director and producer born in Fredonia, New York and owner/operator of "Fourth Ward Productions".  He is represented by "Trailer Park Films" for Canadian commercials and content/media creation.  John Schwert is related to Pius L. Schwert. House on Haunted Hill is a 1959 American horror film directed by William Castle.  The film was written by Robb White and stars Vincent Price and Carol Ohmart as eccentric millionaire Frederick Loren and his wife Annabelle, who have invited five people to the house for a "haunted house" party.  Whoever stays in the house for one night will earn $10,000.  As the night progresses, all the guests are trapped inside the house with ghosts, murderers, and other terrors. The Plagues were an American garage rock band from Lansing, Michigan who were active in the 1960s (not to be confused with other bands of the period named "the Plagues").  They were led by bass player, principal songwriter, and vocalist William Malone.  The group had a local and regional hit with "I’ve Been Through It Before".  Malone left the band in 1966 to join the Frightened Trees, as the remaining members formed a new group out of the ashes of the Plagues, the Plain Brown Wrapper.  Malone later became a successful Hollywood movie director, whose 2008 horror thriller "Parasomnia" included "I’ve Been Through It Before", as well as other songs by the Plagues and other 1960s garage bands.  In the intervening years the Plagues work has attracted a following amongst garage rock enthusiasts and collectors.
