William Castle (The king of gimmick). The film, Homicidal (Alfred Hitchcock Psycho ripoff). The gimmick, the fright break. The outcome, pure entertainment.
Aside from the fright break Homicidal is pretty graphic for its time and definitely surpasses Psycho as far as the blood goes. In one scene a man is stabbed repeatedly in the gut with a big kitchen knife, leaving a bloody mess for all us gore hounds to stare at. We also get a decapitation which is not much by today's standards but in 1961 definitely turned a few stomachs.
Homicidal is a bit on the slow side but is all worth the wait in the end. Castle doesn't disappoint this time around with a twist ending that was totally original for its time. I won't give the climactic twist away because William Castle warned during promotion "Do not give the ending away to Homicidal. If you do your friends will kill you and if they don't I will!"
