Alex Stapleton's documentary "Corman's World: Exploits of a Hollywood Rebel" has an archival, cobbled-together quality not unlike some of Corman's own productions. Some of the interviews with and about Corman reach back many decades, contrasting with wayward footage of Corman on the set of 2010's "Dinoshark" or being honored that same year with a lifetime achievement Oscar. Some of the interviewee omissions are glaring. I would like to have heard from Coppola or Cameron or Towne, for example.
But there's plenty of fascinating movie lore on display here from those who did participate (or from archival footage). Scorsese, who directed his second feature film, "Boxcar Bertha," a kind of hillbilly knock-off of "Bonnie and Clyde," for Corman's company in 1972, recounts an anecdote I always thought was apocryphal: As a follow-up to "Boxcar Bertha," Scorsese presented Corman with the script for "Mean Streets," which he offered to finance if Scorsese would make one change – instead of being about Italian-Americans, make it about blacks. (This was at the height of the blaxploitation movie craze.) Scorsese, after mulling it over, politely declined.
