Barbra never looked prettier than in this movie!

I have only seen her in that romantic movie with Robert Redford and didn't think much about her in term of looks but she was so beautiful here. Impossible not to fall in love with her!

I do think your timeline is accurate, but the reason comes down to hairdo. She had that nice, mousy brown/blond hair worn straight down with maybe a little of that Marsha Brady natural wave toward the bottom. That was a very good look for her. In around 1976 (A Star is Born) she adopted that henna-colored perm that did not suit her very well. It kept popping up in various degrees of fullness and curliness into the '80's.

But by the time she made Nuts (1987) she had a nice hairdo again and that same mousy brown/blond shade. It looked very nice in 1990 (Prince of Tides). Even though she was in her late 40's, I think you have to hand it to her, she reclaimed those nice looks of the early-mid '70's. I also happen to think she looked very pretty in the late '60's. Look back at the footage of her accepting the Academy Award for 1968's Funny Girl (in 1969) - especially that see-through dress. Hubba hubba!

This is the only movie I've seen her in and I found her very charming. Was this mostly thanks to Bogdanovich's direction or does she have that charm in other movies as well?
