Blade Runner 2049
Jack Nelson served as the Oscar-winning visual effects supervisor for Blade Runner 2049, the sequel to 1982's original Blade Runner. Nelson was responsible for the CGI that brought Rachael to life. The process was one of trial and error, done entirely in secret, and it lasted over a year.
Rachael was given the code name "Rita" during filming and shot with a small crew to ensure privacy. First, Nelson and his team created a digital replica of Young's skull. Next, Loren Peta was brought in as Rachael's body double. It took plenty of attempts, but finally, both Nelson and director Denis Villeneuve were pleased with the final result.
