1. Knock-off of Bonnie and Clyde: Producer-director Roger Corman kept his eye on trends, following some and anticipating others. He’d made a few gangster pictures before, but after Arthur Penn’s Bonnie and Clyde became a controversial hit, he saw an opening for another period bloodbath that takes liberties with real-life outlaws.
Thus, the world has Bloody Mama, based on the Depression-era exploits of Ma Barker and her wayward bank-robbing sons. They’d already been featured in a low-budget wonder called Ma Barker’s Killer Brood (1960) and an episode of TV’s The Untouchables; but heck, there’d already been a movie called The Bonnie Parker Story in 1958, and that hadn’t stopped Penn. Many critics saw Corman’s film as a vicious, violent, low-budget rip-off of a vicious, violent, respectable Hollywood hit, and reviewed it accordingly.
