Age Difference
First off, I enjoyed this movie. I liked the commentaries on celebrity ego, male and female relationships, women vs. men and treatment in the news/entertainment world. I'm sure that all of these things were explored rather accurately. However, when portraying an age difference between men and women, a 41 year old woman cannot necessarily play a 35 year old woman. She's great looking. Lovely, slim, elegant. However, skin that has been in the sun does NOT look young. Check the rapid aging of Mel Gibson who was a beautiful young man but has not aged well.
She really did look like she was robbing the cradle. A 13 year rather than a 6 year age gap will do that.
So, same thing that was said for years when older men played opposite much younger women, if it's not in the script, then it loses something and detracts from the movie. And, she was too young for Mark Harmon!
