From the liner notes

An A-list cast showed up to honor the king of B. There are so many clips of shenanigans and boobs from Corman's body of work, that we actually forgot we were watching a documentary. We would be pissed because we were tricked into learning shit, but Roger Corman is pretty damn cool, so we'll let it slide. To top it off Jack Nicholson actually sheds tears while fondly recalling the times he shared with Corman. While it may be aimed at the Cult movie fan, any Joe Fuckface can watch it and feel the culty, titty filled love. Drink it in.
