The Brain (or head) that Wouldn't Die is one of the more thoughtful low budget exploitation films of the early 1960s. It is very difficult to imagine how a script this repulsively sexist could have been written without the intention of self-parody. And the themes that are expressed repeatedly by the female lead, Ginny Leith - a detached head kept alive by machines, I-Vs and clamps - seem to confirm that the film was meant to simultaneously exploit and critique gender stereotypes. Shades of the under-rated Boxing Helena.
The genderisms are plentiful, and about as irritating as an army of angry ants. The dialog is hyperbolic, over-dramatic and unbelievable, and the acting is merely OK (but not consistent). Why have I given this film a 4? Because some thought clearly went into it. I am really not sure what point the film was really trying to make, but it seems clear that it strives for an unusually edgy and raw sort of horror (without the blood and guts today's audiences expect).
Another unique and interesting aspect of the Brain is that there really are not any heroes in this film, and none of the characters are particularly likable.
All considered, this is a fairly painful and disturbing look at early 1960s American pop sexuality, from the viewpoint of a woman kept alive despite her missing body after what should have been a fatal car crash. Her lover is threatening to sew a fresh, high quality, body onto her and force her to continue living with him. She is understandably non-plussed by all of this and forced to befriend a creature who is almost as monstrous as her boyfriend. Oh, there are also some vague references to the 1950s/60s cliché about the evils of science run amok.
