Well you know I always try and think of it like this, most actors when they join a series always prepare for what will happen if the series bombs or gets cancelled right away. But I don't think many are actually totally prepared for when a show becomes a huge success and gets a lot press, and it becomes one of the things they are most recognized for. So when QAF took off the way it did I doubt all the actors were prepared for the show to be so embraced, considering how easily it could have tanked. So to be so associated with just one role you've done over the course of your whole career, especially a role from a television series which can be very hard to escape for some actors, might make certain actors/actresses prickly about the role. I think maybe Hal felt that way about Michael because he always seemed to get very defensive when the character (or the show) was brought up in an interview, he would always sound very surprised by the attention he got from fans because of the role, and honestly being so recognized for just one thing when you've had more then one job would probably be a little daunting and frustrating.
But maybe I'm giving Hal to make credit. I don't know. I just tend to think that his constant clarification that he was in fact straight had more to do with escaping from the role of Michael and being recognized for other things then it had to do with him just pointing out that he was not gay But like I said who knows.
Thats a great point too. I think we're both a little right!!
