Shinichiro Watanabe, director of Cowboy Bebop and Samurai Champloo, directed this short animation that takes place in the Blade Runner universe, some 20 years before the events of the upcoming Blade Runner 2049. In it, a devastating EMP strike is blamed on replicants, leading to a human supremacy movement, and replicants being made illegal.
Check it out, it’s worth a watch.
