Rachael was given the code name "Rita" during filming in order to avoid letting anyone in on the project. Nelson and his team first created a digital replica of Young's skull. Actress Loren Peta was then brought in as Rachael's body double. It took a number of attempts, but by the end, both Nelson and director Denis Villeneuve were thrilled with the final result.
Iron Man
If you compare the first time Iron Man appears on screen versus in films like Avengers: Infinity War and Avengers: End Game, it becomes obvious that animation technology has advanced considerably since his debut. In the original Iron Man film, the production relied heavily on CGI—the 90-pound Mark 1 suit was too unwieldy for both Robert Downey Jr. and his stunt double.
The Great Gatsby
Nearly every scene in Baz Luhrmann's The Great Gatsby involves some sort of CGI. Even the famous Gatsby mansion was entirely computer-generated. Critics applauded the film's visual effects but were ultimately unimpressed by its lack of heart.
