Few film makers have made quite so many movies, worked with so many stars, or introduced the world to so many unknown talents, as Roger Corman did. Then again, few filmmakers have made some of the most schlocky, low budget, ridiculous productions ever to find their way on to the screen. But that is why Roger Corman is a true original, and here are over 10 movies that prove it. These re-mastered productions from the 1950s and '60s are full of blood, aliens, and monsters, not to mention the work of the then unheard-of Jack Nicholson and Francis Ford Coppola.
