Recently, after shooting three episodes of the WGN America drama Salem, an actor in a prominent role left the show for personal reasons. A few years ago, such a major switch would have been a costly debacle requiring expensive reshoots. But “we didn’t have to reshoot at all,” says veteran showrunner Brannon Braga. “We’re replacing his face with a new actor’s face.”
In the early days of CG, Pixar made toys that talked. Now the new toys are often people: Most fans don’t have any idea when filmmakers are shaving years and pounds off their favorite actors, replacing them entirely with digital doubles, or even digitally reanimating their faces: adding a tear where none existed, a look of rage instead of fear.

I thought this was a really interesting article about how far visual effects impact productions at every level.
How far are we really away from say Harrison Ford being able to do a Blade Runner sequel that is few years after the original simply because they can convincingly deage him.
