Anyone who doesn't think Steve Martin is one of the funniest fellows on the planet should have his head examined. As The Man with Two Brains, madman Martin is just the guy to do it, playing Dr. Michael Hfuhruhurr, famed originator of screw top, zip lock brain surgery. The good doctor pines for his late wife - but slinky siren Dolores Benedict (Kathleen Turner) sashays into his life and changes all that. They're soon married, but the truth quickly emerges: Dolores' beauty hides a calculating heart of stone. The situation is hopeless - until another brain specialist's oddball research offers a bizarre ray of hope. Anyone with half a brain will rejoice in the sheer lunacy of this sublimely silly farce, directed and cowritten by frequent Martin collaborator Carl Reiner (The Jerk, All of Me).
