Everyone's eyes will burn as Carrie Fisher walks onto the screen without any CGI Effects.
Why? Last time I saw her on something she didn't look particularly bad for a woman of her age. Assuming the new movies take place ~40 years post ROTJ she'd be just fine as a matronly grandmother type. At least it would be far less likely to see Harrison Ford feel her up onscreen. (just look for it, ROTJ, when they're in cover at the edge of the shield generator. He blatantly grabs and squeezes her breast after she's shot)
