The Oxford English Dictionary defines "B movie" as "a low-budget movie, especially (formerly) one made for use as a companion to the main attraction in a double feature." Corman directed 55 B movies and produced or executive-produced 385 B movies. Among them: Black Scorpion, Bucket Of Blood, Angels Die Hard, Death Race 2000, The Trip, The Wild Angels, The Pit & The Pendulum and The Man With The X-Ray Eyes.
