PolyGram Pictures

Background
PolyGram Pictures was originally formed in 1975 by producer Peter Guber after he left Columbia Pictures as Filmworks, which was eventually merged with Casablanca Records during the production of The Deep and renamed it to Casablanca Records & Filmworks. During that time, the production company was affiliated with Columbia Pictures. In 1977, PolyGram bought out 50% of Casablanca Records & Filmworks, and it was renamed in 1980 to PolyGram Pictures after the PolyGram Records label bought out 50% of the company. Universal Pictures would handle U.S. distribution for a majority of their films through the pact it signed in 1979 (with the exceptions of Wes Craven's Deadly Blessing, Split Image and Flashdance, which were distributed by United Artists, Orion Pictures and Paramount Pictures respectively) while Producers Sales Organization would handle distribution outside the US. In 1982, Peters and Guber left PolyGram to form The Guber-Peters Company which would lead to the deactivation of PolyGram Pictures a year later in 1983. Two years later in 1985, MCA Inc. (Universal’s then-parent company) sold the video distribution rights to the PolyGram Pictures library to Vestron Video as a way of cutting losses due to most of these films losing money at the box office. However, the home video rights to Deadly Blessing would go to Embassy Home Entertainment while the rights to Flashdance would remain with Paramount. Universal would eventually regain the distribution rights to some of the PolyGram films they distributed, which included Endless Love, An American Werewolf in London, King of the Mountain and Missing, among others. Lionsgate holds streaming and TV rights to the PolyGram Pictures-era films (except Flashdance) such as The Pursuit of D.B. Cooper, King of the Mountain and Six Weeks, under license from Hearst Entertainment, which previously had the TV rights to these films via King Features, Lionsgate eventually gained the TV/streaming rights to Hearst's library in 2015.
