Query: Portrait of a pioneer producer

This documentary detailing the fascinating career of the legendary Roger Corman does a great job of showing how much he has impacted the film industry all while being slightly outside its walls. There are many great little lessons to be learned from some industry heavyweights in the interview sections and extras for indie filmmakers. The included film cuts look sharp and colorful and do a great job of keeping the action rolling while providing insight into Roger's producing and directing techniques besides eliciting many moments of nostalgia. I hadn't considered how the era of the blockbuster had affected the drive-in/exploitation industry but this film provides some great insight into this notion. This is essential viewing for film students and fans of Hollywood, I found it inspiring and entertaining throughout.
