It's a testament to Roger Corman's reputation amongst cult cinema fans that people often think of films he only produced as "Roger Corman films." Corman certainly directed his fair share of films, but he was far more prolific behind the scenes, serving as a producer with a keen eye for finding fresh talent and giving those people their big break. In today's world, where auteur theory rules all, it's rare to find a producer who's known to the casual film viewer -- but Roger transcended that. The films his New World Pictures released from its inception in 1970 until Corman sold it in 1983 are known as much for being Corman movies as they are the products of their individual directors. One of the most famous examples is 1975's cult classic, Death Race 2000 -- a title inextricably linked to Corman, though The King of the B-Movies only produced it.
Paul Bartel was the guy who actually got the director's credit for Death Race 2000 -- a beloved film with camp appeal to spare. Corman clearly made the right choice, though -- Bartel takes what could have been a silly story about a cross country car race where the object isn't to just win, but to score points for running down innocent people in the street and makes it ... well, okay, it's basically still a silly story about a race with pedestrians getting run over at regular intervals. It's fun, though -- and when it comes to films from Corman, that's the key.
