Blade Runner is a 1982 American dystopian science fiction noir film directed by Ridley Scott and starring Harrison Ford, Rutger Hauer, Sean Young and Edward James Olmos. The screenplay, written by Hampton Fancher and David Peoples, is loosely based on the novel Do Androids Dream of Electric Sheep? by Philip K. Dick.

Rick Deckard is a "Blade Runner", a special agent in the Los Angeles police department employed to hunt down and "retire" replicants. His ID number is B-263-54, which is stated twice in both the 1992 Director's Cut and the 25th-anniversary Final Cut of the film.

He is the protagonist of the film and the narrator in the original theatrical release.

Agent Deckard was played by Harrison Ford.

Roy Batty is the leader of the renegade Nexus-6 replicants and the main antagonist of the film. He was activated on January 8, 2016, which makes him 3 years and 10 months old by the time of the events of the film. He is highly intelligent, fast, and skilled at combat, and yet still learning how to deal with developing emotions. With an A Physical Level (superhuman strength & endurance) and an A Mental Level (genius-level intellect), he is probably the most dangerous of all the fugitive replicants. He is a combat model, used off-world for military service. He and five other replicants come to Earth hoping to find a way to lengthen their lifespan. He is able to use J. F. Sebastian to get a meeting with Tyrell, the head founder of the company and his creator. Tyrell refers to him as his "prodigal son", and tells him his life cannot be extended, but that he should revel in the life that he has, as he has done and seen things others could only dream of. Following this, Batty kills Tyrell and likely is the killer of Sebastian.
