Wow!
A strong analogy, durasell!
Roger Corman may be known as "The King Of The Bs". I still have a warm spot in my heart for the original "The Little Shop Of Horrors", which was shot over a long weekend.
He also has an eye for talent (Bogdonovitch, Hopper, Scorcese, Coppola, De Palma, John Landis, Ron Howard. All started as "Roger Corman Commandoes") that's been proven to be Second To None.
Jack.
Throw in Joe Dante. And I believe Corman helped out Spielberg in the mid 60s as well.
Corman movies were always fun. They were fun because the people who made them were having fun. War of the Worlds was a big budget death march.
