Is This Trip Really Necessary?

The "trip" of the title is induced by LSD, consumed by a couple of nubile film actresses at the behest of realism-obsessed director John Carradine. Hero Peter Duryea attempts to rescue the girls, but both are doomed to horrible deaths in a lovingly detailed torture-chamber set. Eighteen-year-old Carol Kane (here billed as Carole) was evidently offered no acting advice whatsoever by her veteran co-stars Carradine, Duryea, and Marvin Miller.
