Liz really was gorgeous when she was young. She's lived pretty hard and had a brain tumor so I guess we can cut her some slack.
The others, lord only knows.

I think today's stars pretty much pale by comparison. Part of it is we simply know too much about their lives. But also, they've spent so much time fucking with their bodies, who knows what they really look like.
