Journey Into The Beyond (1975) [4k Restoration] [Blu-ray]

An apparent investigation into the fringes of psychic spirituality with so-called real experts, exorcisms and seances, be warned Journey also manages to be a very sleazy cocktail indeed. There's many a grotty scene of real brain tumor removal and animal cruelty. An unforgettable scene offers a Third-World doctor yanking out cancers from his patients using his bare hands and no anesthetic. Imdb.
