How she looks now v. the older Lorraine in BTTF
In the Back To The future series, Lea Thompson was "aged" about 25 years via make-up. She's now a little older in real life than the age that she portrayed as the older Lorraine McFly.
The make-up guys missed big on this one. I guess the assumption was that she would have a fuller face, and a frumpy figure.
To me, Lea's face today is thinner than when she was younger, as in Red Dawn and Some Kind of Wonderful. I never really found her attractive when she was younger. She had the type of build that one could see progressing to heavier hips and thighs and the loss of a figure as she got older. It even states in her bio in IMDB that Mikhail Baryshnikov said she was too stocky when she was a young ballerina.
I think she looks just fine now for her age. I believe she has aged well.
