Invasion of the Bee Girls (1973)
William Smith is a towering, musclebound character actor who paid his bills by portraying bikers, sadists and various loose nuts in crucial cheapies like THE LOSERS and DARKER THAN AMBER. His red hair and action figure physique make him recognizable from about nine miles away, but here he shifts that comic book bravado to play a straight-laced government agent investigating nefarious doings.
It appears that men have been dying from “severe sexual exertion,” and all roads lead back to a shady lady scientist with a penchant for bee research. (Zack)
