What type of literary adaptation is Blade Runner recognized as?

Blade Runner is recognized as a novel to film adaptation because it is based on Philip K. Dick's science fiction novel, "Do Androids Dream of Electric Sheep?" which was published in 1968. The film, directed by Ridley Scott and released in 1982, translates the themes, characters, and narrative elements from the novel into a cinematic experience. This type of adaptation involves taking the original story from a written format and reinterpreting it visually and thematically for the screen, which is what Blade Runner successfully accomplishes.

This distinction is important as it highlights the creative process of transforming literature into film, including the changes and reinterpretations that may occur to better suit the medium of film. Other options, such as film to novel or play to film, do not correctly represent the origin of Blade Runner as the narrative source is ultimately a novel, making the choice of "novel to film" the accurate designation.
