This curiosity, long unavailable in any form in the U.S., has been dissed even by die-hard fans of director Russ Meyer. It’s hard to see why — Blacksnake! is no more or less bizarre than his other movies. Made shortly after his tawdry big-studio flop The Seven Minutes, it initially seems to be a departure for the filmmaker: a period piece about slavery in the 19th-century West Indies. But then the Meyer touch busts out: The slave driver is a lusty blond sadist. As is common with late-period Meyer, Blacksnake has a mind-blowingly inconsistent tone, going from earnest to imbecilic as fast as one of his trademark edits. When the Emancipation Proclamation is read over slo-mo shots of interracial couples running naked, all you can do is guffaw.
