I don't think it's fair to say "She had time, she could have done it" when we have no idea what her life looked like. Or if she even wanted to do it, which would be a very valuable reason for her to say "Thanks, but no thanks". She owes us nothing.
You seem to assume everyone can handle the same amount of work. But not everyone can do that. Or want to.
Even if she wanted to do interviews, maybe she just didn't have the energy.
Not that I get why she would, since she probably did other interviews and such, and after all, how much time can people spend working and talking about their work before you start hating it, even if it is your dream job? From what I gather, popular actors have crazy lives, that would make me start to drink or pop pills. Filming the same scenes over and over again, doing interviews from time to time, having a personal life, having to get up at weird hours, waiting to film, filming the same scenes over and over again, and again and so on. I can imagine wanting to squeeze more into that. I mean, a commenteray might have to be done several times as well, to get it good. And not only would she have to talk for about 40 minutes, she would do so scriptless, maybe tired while having to sound like she wants to be there.
No clue if she thinks the way I would, but all in all, I can't blame her, whatever her reasons are. Even if they're just that she's not interested enough. It's her life after all. If someone called me a diva because I didn't want to work extra to please people I don't know, yet work hard for anyway to bring entertainment to, I'd be a bit unkind in my answer (and again, I repeat, this might not at all be how SMG thinks. Maybe she loves her fans a lot and are very sad she couldn't do extras).
I never said she was a diva first off. I understand all this as well but as an actor/actress you know what you are getting into. If you become successful and a big star you know you are going to be busy. So my thing is that really isn't an excuse in my eyes. That is like when celebrities complain about the paparazzi for example yes they are wrong sometimes but that is the way of the business you choose it simple as that. I am not dissing Sarah and I understand she may have had reasons but then again it is just a little odd when thinking about it how she couldn't fit in one interview. Some people are traveling non stop doing movies at the same time and she couldn't do one a season or one a few seasons? It is just a little weird. Again I understand everyone is different I just think the excuse that she was always busy doesn't fly the whole time.
About the other interviews I have seen Shania Twain do at least like five interviews all of the same topic in a week is it boring to listen to over and over again? Yes kind of but she wrote the book knows she has to promote it and does her job.
I also like to think the crew works just as much if not more. The writers are constantly working. I watched extras on Smallville and did not realize it took that long to do a script yet they sit down. Call me crazy but I think being a writer of a hit series is a little more difficult than being an actor.
