Ah, The Incredible 2-Headed Transplant (1977). The recipe, you ask? Take one large body (the late John Bloom, one of the tallest actors to ever grace the screen at 7’4″) named Danny, a simpleton. Add the, ah, head of a psychopathic killer (well-played by Albert Cole), and watch him shake off the restraints and drugs plied to him by the scientists. Shake thoroughly and then just throw it in the garbage, because, despite the efforts of a fair cast, including Bruce Dern, this is a real stinker. Bad title, bad use of women, bad treatment of experimental subjects, bad depiction of bikers. Bad, bad, bad[1]. OK, the special effect of a two headed man actually wasn’t awful.
And you have to appreciate the movie poster, as it really embodies the entire exploitation movie making regime of the time. I mean, really, to quote my Arts Editor. Uff-da.
