Thompson purchased Roger Corman's independent production company New World Pictures in 1983. Thompson eventually left the company a year later, and Kuppin and Sloane as both executives of the "New" New World Pictures, they were able to branch the company into three new divisions. New World International handled the motion pictures done outside the United States. New World Television handled TV shows and made for TV motion pictures; and New World Video handled the video distribution of all of New World Pictures products. New World also purchased the Marvel Comics division in 1985.
New World Pictures made a major impression with producing and distributing motion pictures around the world. Some of the films included the "Hellraiser" series and the critically acclaimed black comedy "Heathers". From 1983-1990, New World Pictures produced nearly 150 films. Unfortunatly, by 1989 New World Pictures went into a downward fall with financial problems.
