Not copyright. U.S. release through World Entertainment Corp./United Pictures: November 1966. U.K. release through Compton-Cameo: February 1967. Banned in Australia. 7,241 feet. 81 minutes.SYNOPSIS: Six people are summoned to a remote Caribbean island for a reading of a disfigured chemist's will. The chemist's ghost informs the heirs that one of them was directly responsible for his disfiguration. That night, the chemist's doctor is murdered. The housekeeper is also fatally attacked. Before dying, she explains that her master had created an electronic monster who has been programmed to kill the heirs one by one. COMMENT: Even rabid Virginia Mayo admirers will be hard put to glean much satisfaction from this cheapjack "attraction". Not that the fault is Miss Mayo's. It's rather the ploddingly unexciting script and mindlessly static direction that are chiefly to blame for the movie's almost total lack of suspense. In fact, the only player who comes across with credit is Shelley Morrison who corners all the most colorful scenes and has all the attention-grabbing lines. The director seems to like her too. She gets just about all the close-ups - only the monster runs her anywhere close. OTHER VIEWS: Any hopes aroused by the tensely ingratiating confrontation between Natividad Vacio and Shelley Morrison in the pre-credits Prologue, are quickly dashed by a couple of exceptionally tedious scenes of boring exposition before our travelers are eventually ensconced in the title castle. Even the robotic zombie as woodenly enacted and none too convincingly made up, fails to inspire much interest, let alone terror. The plot invention leading to the monster's final demise is introduced with all the subtlety of an elephant stampede. Penny-pinching production values and an abrupt conclusion don't help either. - JHR writing as George Addison. Lyon's direction is so labored, the film sinks without trace, despite competent performances from Scott Brady and Hugh Marlowe. - Monthly Film Bulletin.

A bunch of hopeful heirs to the estate of a reclusive but wealthy scientist arrives on an isolated island to hear the will. The sinister housekeeper, Lupe (well played by Shelley Morrison) turns out to be in cahoots with the horribly scarred scientist. But there is a murderous, equally horribly scarred zombie robot the scientist has made in his own image that threatens and / or starts killing some of the assembled heirs. It becomes a race against time for the survivors to uncover the person responsible for the scientist's disfigurement, to call off the rampages of the robot. The story has some nice touches but the soap opera dialog and unpleasant characters keep Castle of Evil in constant low gear. It is good to see the underrated Lisa Gaye but her character is so dull. Hugh Marlowe and Scott Brady are well cast, and Brady provides a tongue in cheek attitude when he keeps referring Lupe as 'Loopy.' Virginia Mayo is terrible, and she seems to know it... The zombie is menacing, however. As played by William Thourlby, the zombie scientist only has to cock his head slightly to be frightening. (Thourlby was the star of the lamentable Z-movie, The Creeping Terror.) Paul Dunlap's music is not boring and kept waking me up. The secluded castle has many unusual features, including an elaborate electronics and surveillance system.

I had originally seen this on creature features on channel 5 in new jersey and back then it was scary,recently re watched it on you tube,in a very well recreated creature features with commercials.just like i remembered it,a creepy old chiller.back in the day this was scary.old castle,secret doors,a ghoul,and yes a player piano.with some good actors in it led by the late great Scott Brady(destination inner space)Lisa Gaye(shake rattle and rock)Virginia Mayo(white heat)and Hugh Marlowe(day the earth stood still)i enjoyed this little horror flick even though its no masterpiece and not as good as the original house on haunted hill.but it does have its moments.they don't make them like this anymore and if they tried remaking it there would be lots of overdone cg effects,6 pout of 10.

"Castle of Evil" is haunted castle movie much in the style of Roger Corman and England's Hammer productions. Although it doesn't quite measure up to those productions, it is a competent little horror flick. The story involves a group of people who are summoned to a mysterious castle for the reading of the will of the man who has virtually destroyed each of their lives individually. Their host unfortunately has just passed away, or has he? The film contains most of the usual horror cliches and settings. There are the secret passages, sliding doors, dark shadows, murders and the requisite mysterious housekeeper. The film is boosted by its veteran cast of actors who had all seen better days but were still able to deliver solid performances. Scott Brady is the hero of the piece and Virginia Mayo effectively plays a discarded mistress. Hugh Marlowe is along as a doctor, David Brian as a lawyer and the lovely Lisa Gaye as Brady's love interest. Shelley Morrison is quite good as the housekeeper. What now makes this film memorable is the resemblance of the character "Kovic" to a certain former U.S. president. See if you agree.
