The same year (1982), Hauer appeared in arguably his most famous and acclaimed role as the eccentric and violent but sympathetic antihero Roy Batty in Ridley Scott's 1982 science fiction thriller Blade Runner, in which he delivered the famous tears in rain monologue.[25] Hauer wrote some of the speech himself, the night before shooting, "cutting away swathes of the original script before adding the speech’s poignant final line".[26]
