On the contrary, it's a great analogy. In sports, the name of the game is drawing fans to the stadium. In acting, the name of the game is drawing an audience to the theatre. In sports, a team draws fans to the stadium by winning. In acting, one way to draw an audience to the theatre is to feature attractive young women in a film. If an athlete can no longer contribute to the team in a way that draws the fans, the athlete should be let go. If an actress no longer has the looks to draw an audience, another actress should be cast in her place.
It may not seem fair, but it's reality. As I said in my previous post, I doubt any of these women were complaining when they were the ones benefitting from this reality fifteen years ago.
The fact that they've made huge sums of money before their fortieth birthdays is all the more reason why they have no justification to complain. If they haven't properly planned for a time when the big contracts won't be there, that's their problem. No one who makes millions of dollars playing pretend gets sympathy from me when the pretend game goes away.
Yes, that's one way. The other is for the audience to be thinking ABOVE the waist. Obviously, that concept is lost on you.
