Query: Underrated Horror Cult Classic

Narcissistic Joan Crawford in an overlooked role runs a circus that can only be described as psychopathically appealing. You see, so many of her employees end up dead! Director, Jim O'Connolly shows great flair for the genre. It's all just a matter of who gets killed next. British veteran Michael Gough, British cutie Judy Geeson in her film debut and the handsome and heroic Ty Hardin are all on hand. It's a great film for Halloween season. Joan Crawford seems to have always had problems managing her business concerns ever since "Mildred Pierce." "Berserk!" is aptly titled!
