The ultimate cinematic head trip of the 1980s, British renegade Ken Russell's first Hollywood production adapted by the legendary screenwriter Paddy Chayefsky from his own novel is part hallucinogenic freak-out, part gonzo creature feature, part transcendent love story, all played at a fever pitch. When researcher Eddie Jessup (William Hurt) begins using himself as a test subject for his mind-expanding psychological experiments, it sends him on an increasingly dangerous, substance-fueled odyssey from humankind's primordial past to the outer limits of consciousness. It's all visualized by Russell in a psychedelic supernova of out-there imagery that encompasses everything from the pagan to the cosmic sublime, culminating in a brain-wave-blasting battle between the mind and the heart. | Altered States (Criterion Collection) | | 4K Blu-Ray | 4K Ultra HD Blu-ray | Best Buy
