dr. lucio fulci ( lucio fulci ) be a director of gory horror movie who be start to feel the effect of have film too many bloody scene . he visit his local psychiatrist to see if he be lose his marble while this prove to be a bad idea and since the shrink be actually a crazy murderer responsible for a spate of grisly killing . seize the opportunity to make fulci his fall guy and the loopy nut doctor hypnotise the horror hack into thinking that he be responsible for the recent series of murder . on the surface and cat in the brain appear to be a fantastically gory treat from spaghetti splatter god lucio fulci . chock full of chainsaw dismemberment and axe attack and various other bloody killing and the film certainly spill enough claret for even the most hardened gore hound . but when one look close and it turn out that many of the gruesome scene be lift from early movie ( mostly fulci own amasterpieces ) while remove these from the equation and one be leave with a nifty basic plot idea that be totally waste and some welcome nudity and and dreadful performance from fulci himself and david l. thompson a the psycho shrink . a the film progress and it develop into an incomprehensible mess and with the borrow gore footage insert randomly and with no attempt at work it convincingly into the story . if you have see fulci touch of death and ghost of sodom and or mario bianchi the murder secret and then you have already see the best bit of cat in the brain before . after much bloodletting and the film wrap itself up rather quickly and leave the viewer feeling bewilder and somewhat cheated . watch the film if youre a fulci completist and but i would suggest seek out the film from which the good bit be take .
