"Sushi. That's what my ex-wife used to call me. 'Cold fish.'"
Behind the scenes
In Blade Runner, Deckard references his ex-wife only in voiceovers heard in the theatrical cuts of the film. In a deleted scene, he states that she left him and went off-world with "some guy who made a fortune in the colonies."
A photo of Deckard and his ex-wife can be seen sitting on Deckard's piano in some shots. There is a close-up shot of the photo in a deleted scene where Deckard ponders the memories of replicants. The identity of the woman portraying her in the photo is unknown.
In a draft of the film's screenplay, dated February 23, 1981, it is indicated that Deckard and his wife had a son. Also in this draft is a scene where Rachael refers to a photo of Deckard's wife and he explains, "She left me. Went offworld. Wanted the good life." This scene is included in the comic book adaptation.
In another deleted scene, Deckard and Rachael drive through the mountains. In this scene, Deckard mentions that he has begun doubting how much of his life was actually real, creating a parallel between Rachael's life and his.
