Devil Times Five (1974)

One of the most insane horror epics from a decade known and loved for its insane horror epics, Devil Times Five (1974) chronicles a quintet of homicidal maniacs who escape from their loony bin and descend on a ski lodge, where they terrorize three couples vacationing, oftentimes to death. The kicker: the killers are all kids. The toxic scamps are led by Sister Hannah (Gail Smale) and include dandy narcissist David (Leif Garret), military obsessive Brian (Tierre Turner), and adorable pyromaniac Moe (Dawn Lyn, who played freckle-faced Dodi on My Three Sons). The monstrous moppets rain death down on the resident adults by axe, piranha, bear traps, a pointy stick, and slow-motion bludgeoning. En route to being diabolically dispatched by prepubescent psychopaths, Joan McCall and Carolyn Stellar bare their most interesting adult parts.
