Cult director Frank Hennenlotter (1982's "Basket Case") turns his gleefully demented imagination free on this tale of Aylmer, a mutated parasite with an appetite for brains. Emmy-winner Rick Hearst ("General Hospital) stars as a young innocent who gets the headache from hell when the creature takes over his life. To keep his diet of brains coming, Aylmer addicts Hearst to a hallucinogenic he produces after feeding, leading to some truly amazing fantasy sequences and zonked-out, self-referential humor. Legendary horror host John Zacherle provides Aylmer's voice. Includes censored scenes.
