Trivia

Financed by Amicus pictures in 1970 as "Romeo and Juliet '71" in an attempt to capture the ever-growing grindhouse/exploitation market. The experiment worked too well, as the final product proved to be too nihilistic for Amicus executives, who were still used to the more benign, supernatural films they had produced in the 1960s. Amicus shelved the film for two years until it was picked up for distribution by 20th Century Fox, who successfully marketed the film on the American grindhouse circuit.

When first announced, Sir Ralph Richardson and Sir John Gielgud were also set to star.

Final film of Patricia Fuller.
