Burroughs' treatment is set in the early 21st century and involves mutated viruses and "a medical-care apocalypse".

and not the Nourse and Burroughs source material, although the film does incorporate the term "blade runner", though with a different meaning from in the novel.

Blade Runner (a movie) was loosely adapted as the 1983 film Taking Tiger Mountain, after co-director Tom Huckabee purchased the rights to the novella from Burroughs for $100.
