“Little Shop of Horrors” (1960)
The extremely low budget original movie from film titan, Roger Corman. It was written over a single weekend and filmed over two days on a leftover set. Features an early role for Jack Nicholson as the dental patient who would later be played by Bill Murray. Its lapsing into the public domain allowed the production of the popular musical and the '86 Rick Moranis/ Steve Martin remake.
