Filmgroup was a production and distribution company founded by filmmakers Roger Corman and Gene Corman in 1959. Corman used it to make and distribute his own movies, as opposed to ones he was making for American International Pictures. The company ultimately folded but lessons from running it helped Corman make a success later of New World Pictures. Filmgroup also produced early feature work of Francis Ford Coppola, Peter Bogdanovich, Charles B. Griffith, Curtis Harrington, Jack Hill, Monte Hellman, Robert Towne and Jack Nicholson.
Corman established his own company, Palo Alto Productions, in 1954, which was responsible for his first two movies. Filmgroup came out of a desire for Corman to move into distribution.
The first films they distributed consisted of the double bill, High School Big Shot and T-Bird Gang, movies which Corman had executive produced and helped financed. Corman would also buy films made by independent distributors, in addition to several films from the Soviet Union, which he would re-dub and have additional scenes shot and added to.
Corman never bothered to copyright the movies so most of them are in the public domain.
