Throw in Joe Dante. And I believe Corman helped out Spielberg in the mid 60s as well.
You're quite right about Joe Dante. Borges.
Couldn't remember his name. Spielberg caught Corman's eye while Spielberg was at USC.
What was cool about Corman was that he'd write, direct and make a film. Sell it to distributors for strings of Drive-Ins. Take that money and make another film. A simple procedure that worked. Over and over again.
I guess that after attaining an Engineering Degree, Corman hated to waste time and money. Historically, Corman almost always brought in films under-time and under budget.
Jack.
