Rogue One's use of the character of Grand Moff Tarkin, as played by Peter Cushing is an impressive next step in the use of CGI to allow filmmakers to be able to utilize actors who have either passed away, or need to be shown at a far younger age. In Cushing's case, he had died back in '94, which left filmmakers with only a few options: not use the character at all, to recast, or to utilize special effects to see how far through the uncanny valley the industry has progressed.
