So hair seems to play a much bigger role in characterizing characters in 80’s films than it does in film today.
Here are some examples:
In Fatal Attraction Glenn Close plays a crazy woman and thus her hair is pretty extreme. Through much of the movie it looks like you possibly shoved a finger in a light socket. It seems to get bigger the crazier she gets. You can compare this still of her first meeting with Douglas’ character:
where her hair is at least pulled away from her face and somewhat tame, to this photo as the movie has progressed and she has completely lost it:
Seriously. She looks like someone styled her hair with some sort of electric shock instrument. It has become an entity unto itself. She literally could not play a sane person with this hair. I would not believe it.
In The Big Chill her hair is curly, but it is styled into tight coils rather than frizzy craziness:
and in Jagged Edge, it is beyond tame. Smooth and styled to perfection:
Essentially her hair changes texture and style in extreme ways for each film, and this is not counting the period films she did in the 80’s. This is a huge contrast to an actress of today like Jennifer Aniston who has had literally the same hairstyle for almost every movie she has ever done.
