Trivia: Originally, Alejandro was meant to have much more dialogue, and his tragic origin would have been revealed earlier in the film. Actor Benicio Del Toro and director Denis Villeneuve ended up agreeing that the character worked better as a silent, mysterious type and that the revelation of his origin should occur late in the film. It is estimated that as much as 90% of his dialogue was deleted during rewrites.
