I'm watching Devil Hunter after recent Jess Franco watches Death Whistles the Blues, Mondo Cannibale and How to Seduce a Virgin.

I'm immediately struck by that zoned out, robotic but entrancing acting that characterizes later Franco. He admits that he asked untrained actors to do as little as possible because he didn't have time to coach them properly as actors. But when he had budgets and time, he got amazing performances quite steadily. Franco is the quintessential fast shooter of quality.
