15 Huge Controversies That Rocked Star Wars

4. CGI Tarkin

In recent years, Hollywood's tentpoles - and in particular Disney's blockbusters - have revelled in their new-found ability to convincingly de-age actors digitally for the first time, ostensibly making them all evergreen. They did it to Michael Douglas in Ant-Man and then Robert Downey Jr in Captain America: Civil War, and it was clear they had the skills.

As a side-development, the studio obviously also realised that they could effectively bring long-dead actors back from the dead - such were the technological advances made in digital character building. Unfortunately, while establishing that they COULD do that, they never stopped to wonder whether they SHOULD.

So when Peter Cushing was revived for Tarkin's scenes in Rogue One, what was supposed to be a moment of pure fan-baiting quickly became a rare blemish on the film's success. It's fair to say it pissed off a lot of people - partly because the CG wasn't all that great, but mostly because it was deemed disrespectful.
