Frederick Wiseman (born January 1, 1930) is an American filmmaker, documentarian, and theatre director.
 His work is "devoted primarily to exploring American institutions".
 He has been called "one of the most important and original filmmakers working today".
High School is a 1968 American documentary film directed by Frederick Wiseman that shows a typical day for a group of students at Northeast High School in Philadelphia, Pennsylvania.
 It was one of the first direct cinema (or cinéma vérité) documentaries.
 It was shot over five weeks in March and April 1968.
 The film was not shown in Philadelphia at the time of its release, due to Wiseman's concerns over what he called "vague talk" of a lawsuit.
Titicut Follies is a 1967 American Direct Cinema documentary film directed by Frederick Wiseman and filmed by John Marshall, about the patient-inmates of Bridgewater State Hospital for the criminally insane, a Massachusetts Correctional Institution in Bridgewater, Massachusetts.
 In 1967 the film won awards in Germany and Italy.
 Later on, Wiseman made a number of such films examining social institutions (e.g. hospitals, police, schools, etc.) in the United States.
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.
State Legislature is a 2007 American documentary film directed by Frederick Wiseman.
 It details the workings of the Idaho Legislature.
 Wiseman filmed for a total of 160 hours over a full 12-week session of the legislature, later editing his content down to a 3 ½ hour film.
 Wiseman was interested in the topic as a way to show one of the more basic political systems in America at work.
 It was first broadcast on PBS on June 2007.
William Malone (born 1953) is an American horror filmmaker who directed such films as the 1999 remake "House on Haunted Hill", "Scared to Death", "Creature", and "FeardotCom".
La Danse: The Paris Opera Ballet (French: La danse - Le ballet de l'Opéra de Paris ) is a 2009 French documentary film directed by Frederick Wiseman.
 Besides aiming to reveal "how the company functions as an organic whole", the film follows the production of seven ballets by the Paris Opera Ballet.
 The ballets featured are:
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.
Law and Order is a 1969 documentary film by Frederick Wiseman that shows the daily routine of officers of the Kansas City Police Department.
 It was Wiseman's third film after "Titicut Follies" (1967) and "High School" (1968).
 The films were among the earliest examples of direct cinema by a U.S. filmmaker.
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.
