I have a hunch 20th Century-Fox didn't take Roger Corman too seriously when he said he would adopt a semi-documentary approach to the St. Valentine's Day Massacre. They'd heard that story before from good old Rog. Like the time he told American-International he'd like to do a semi-documentary on motorcycle gangs and what he made was the sex-and-sadism money-maker of the year, "The Wild Angels."
