I'm setting my novel in the early 1980s, specifically in the middle of 1982. My protagonist takes a girl to see Blade Runner, which was released on June 25th, 1982. I mention advertisements for the film's release early on in the novel. The plot circumstances involves him being coerced into killing, which throws into question his connection to the rest of humanity, and I'd like to have him think on the Voigt-Kampff test and nature of replicants. My question is: can I do that? Or would that be in violation of copyright rules?
