What I wanted to write this time, is that there is a difference about fan serice between men and women. This derives from the media that all most all the Hollywood stars who do fan service a lot, are men.
Precisely, they don't hate to stay in public because they aim to be actors & actresses. Some people might say it's different movie and reality; however, there are a lot of people in shooting.
Is it difference of strength between men and women? It is true that there is difference between men and women about strength. But it's not important regarding fan service.
Conclusionally, it might be biological difference. In short, men can be much friendly than women when they confront general public.
In considerarion about this, I think this may true to some extent. In bad terms, it is "imprudence" while it is "friendly" in good terms. For example, isn't it men who talks first when men and women are in new class in new school year? (Extremely seduction is this.)
The result of this phenomenon, I don't know if this is true or not, all most all the long-term actors are men nevertheless it is USA or Japan. For example, is there any actress who is still in same level (in terms of publicity or fee) with Clint Eastwood who is in his 70's.
How about actresses compared with Al Pacino, or Gene Hackman who are in their 60's. As far as I know, the oldest actress who is still in forefront of Hollywood, is Meryl Streep who is in her 50's. The next generation is Jodie Foster or Julianne Moore who are in their 40's. In this age, there are plenty of actors. It is quite different in their 30's or 20's.
There might be the reasons such as pregnancy and birth, however, the difference is too big.
