Blood Maniac (lost horror film; 1986)
Blood Maniac is a 1986 Hong Kong horror film directed by Wilson Tong (under the pseudonym Wai Sing Tong).
A man brings home his new wife and is faced with an icy reception from his parents. His devil-worshipping brother has recently died, but the warlock’s spirit is haunting the house. Soon the man becomes possessed and (somehow) creates a “mental link” with a zombie buried in the backyard.
As of currently, there are no resurfacing home video releases, theatrical posters, screenshots, or any footage floating on the internet. The only piece of media that could mark its existence is the opening title credit of the movie (presented vertically in a white border).
