One of the well known tie-ins to the Blade Runner film is the Blade Runner comic. It was issued in two volumes and a combined edition.
The Blade Runner comic is very interesting for its interpretation of the movie. Quite obviously, they can’t possibly do the same in a comic as in a 2 hour movie, so one expects that some dialogue will be trimmed or even slightly changed and details in the action will be curtailed or perhaps adjusted. One of the things I find most interesting is that some of those differences from the original movie version are referencing the shooting script! So, while there is some interpretation and a particular perspective present, it is in some ways almost like a different cut of the film.
