There's a certain kind of sexism at play in how women in Hollywood are viewed as actors. Okay, there's a lot of sexism, but I'm only going to focus on a certain part of it today. Think about the last film you saw involving a romantic relationship onscreen. How old was the male actor compared to the female actor? Generally there's an age gap, with the man being older and the woman being younger. This is such a trend that it's a gag line in the trailer for the upcoming film Last Vegas.
Now, I don't mean to criticize age gaps in couples. I for one am a 22-soon-to-be-23-year-old with a massive, crippling crush on a 32-year-old actor. I had a friend whose parents have a 10 year age gap between them. I have friends who have dated people older or younger than themselves. It isn't necessarily about the gap, but the fact that Hollywood continually makes the gap only between an older man and a younger woman and heavily criticizes women - such as Demi Moore when she was married to Ashton Kutcher - who are older and date younger men.
Again, I'm usually not terribly concerned about age - unless I know the couple personally and I have a legitimate reason to be concerned. Or in the case that it's harmful or exploitative to one of the parties involved (AKA: pedophilia. Major problem). I generally assume it's up to a couple to figure things out, and if they're in a relationship that's more than just about sex or money or appearances, and they really care about each other and having a decade or two between them isn't a problem, then whatever; I'll try to stay mum on the issue. However, society and history has built up a lot of reasons for why I feel uncomfortable about age gaps of certain sizes between men and women - creepy arranged marriages of young girls to men older than their fathers, men leaving their partners for younger women, the idea of having a trophy wife or someone who looks continually young, the obsession we have with youth, the fact that women can be mocked for whatever age they are attracted to. Attracted to someone younger? Wow, you must like immaturity or have an obsession with youth or prey on young men. Attracted to someone older? Wow, you have a complex with experience and authority or you just care about social position and money. Apparently if you don't find a partner within whatever specific designated age range society finds acceptable, you fail.
To reiterate, yes, birds of a feather flock together and relationships between 900-year-old time lords and young women may likely end in tears.
Too soon? Too soon.
But the point being is that Hollywood continues to portray heterosexual relationships in a very limited age format, which is rather annoying and harmful to women's already less than perfect treatment in film. Men are encouraged to have such relationships while women are mocked for it and told they have to stay young or else they cannot be considered a love interest. And now other forms are continuing this way of thinking and... well, it's a problem. And one all the more complex when age itself is complicated on its own.
