One of then great titles of all time for what was essentially the final film in the AIP beach party cycle, in spite of the fact that most original cast members had all already moved on. Even the great Buster Keaton was replaced by (the also great) Benny Rubin in this one. Tying in to the horror craze, Basil Rathbone and Boris Karloff appear and seem to be having great fun. Tommy Kirk and Deborah Walley are the ostensible leads with Aron Kincaid and Harvey Lembeck in their traditional antagonist roles. Some clever spfx shots!
