(The reason is that AIP required films to be shot using union crews; working on his own, Corman could save money by going non-union.)

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.

Their first movies were High School Big Shot (1959) and T-Bird Gang (1959) produced by Stanley Bickman.

Because Roger Corman often neglected to copyright his movies, most of these films are in the public domain.
