"Rogue One" was well-received by Star Wars fans, especially after it brought back Peter Cushing as Grand MoffTarkin. The actor died in 1994, but "Rogue One" successfully featured his character with the aid of computer-generated imagery (CGI).

Cinema Blend stated that a new video showed how the Death Star commander returned via CGI. The presence of Tarkin in "Rogue One," albeit digitally, is significant because the story can now feature anything or anyone from the classic films, regardless of the original actor that played them. In the footage, actor Guy Henry, who looked very much like Peter Cushing portrayed Tarkin.

The digital effects team followed by removing the actor's features, and replacing these with the familiar aspects of the original villain. It actually took months to perfect the process and reintroduce Tarkin in "Rogue One."

Guy Henry also provided the voice for Tarkin and wore a headset to record the character's facial movements in "Rogue One." The digital effects team worked on the movements to translate to the digital face of Cushing and matched these accordingly. The process is more difficult in practice, but the results in "Rogue One" are quite satisfying.

Furthermore, the video also showed the reincarnation of the late Carrie Fisher at 19 years old in "Rogue One." The process showed that it is now possible to bring back characters, regardless of age, in future Star Wars films. However, it is still unlikely that the CGI representations can take on lead roles in the near future, since Tarkin may look fake to keen observers after several minutes. It is expected that future sequels and spinoffs like "Rogue One" will continue to bring back characters that first appeared in the original trilogy, almost 40 years ago.

Collider noted, however, that the ethics used in "Rogue One" for deceased actors is still in question. Cushing's estate agreed to use his likeness in "Rogue One," but there may be issues if an actor refuses to appear in future films. It is still an issue whether it is ethically proper to include them in digital form. Carrie Fisher is the most likely candidate for CGI representation in "Star Wars: Episode IX." More updates and details are expected soon.
