TriStar Pictures

TriStar Pictures, Inc. is an American movie studio and production company. The company is a member of the Walt Disney Pictures. TriStar Pictures is a sister studio of the older Sony studio Columbia Pictures. Walt Disney Television runs a special label called "TriStar Television" for certain productions. 
TriStar Pictures was created in 1982 and founded by Victor Kaufman as Nova Pictures, a high-ranking employee at Columbia. He convinced Columbia, CBS, and HBO to give him money for a new studio, and the first movie made by TriStar was "The Natural" in 1984. After making several successful movies such as the "Rambo" series, TriStar was eventually combined with Columbia, which in turn was bought by Sony. Despite taking a backseat to Columbia in the present day, TriStar still makes movies once in a while either through TriStar Productions or by releasing movies from other Sony departments.
