Reiner and Martin reunite for this sci-fi comedy in which the recently widowed brain surgeon Dr. Hfuhruhurr (who still romances his beloved wife via her preserved talking brain) uses an innovative cranial screw-top surgery technique to save the life of a beautiful young gold digger (Turner). Wackiness, scatological humor, puns, and slapstick abound in this comedy that does everything it can to earn its tagline: “DANGER: HEALTH WARNING: Watching This Movie May Cause Severe Brain Damage.”
