It is a cinematic triumph. Peter Cushing himself called it his greatest role! Well, he might have said that.
Fun fact that I actually just learned today. The cast made from Mr Cushing’s face for his scene in Top Secret was used by the SFX wizards working on Rogue One to digitally recreate the actor for the movie.
Imagine that, a casting for a prosthetic made over 40 years ago was used to recreate the image of Peter Cushing so that he could appear as Grand Moff Tarkin again.
Have to admit, that rather stunned me when I read it.
I have to agree with you.
Actors that have been “de-aged” or simulated just don’t quite cross the uncanny valley for me. I loved Tron Legacy, but the de-aging on Jeff Bridges was just off. So those scenes with CLU and in the past just drew me out of the film.
