I haven’t seen the movie, but I’m still trying to figure out what Mark Bingham being gay has to do with the story.
Not as often mentioned (and just as irrelevant to the story of Flight 93): Mohamed Atta, the leader of the 19 hijackers, was also probably gay.
Scott - this is only my opinion, btw - I saw the movie (and watched it again last night) - the whole Mark/gay thing wasn’t “handled” or really even addressed as a salient point to the story - he was portrayed as another passenger - with family, fears, friends, etc. - the only thing that stuck out for ME was that he had to run to make the plane - had he been just a few minutes later, he would have missed Flight 93. 
I didn’t see them focusing ANYthing on his sexuality.
Then again, I can be a bit of an idiot - so if I’ve missed some huge thing someone else saw, I apologize.
I caught this movie last night. It wasn’t too bad, actually. I was pleasantly surprised. The only thing that got a little annoying to me after a while was the over-emphasis on the children who were left behind. Yeah, we get it. That sucks. But you don’t have to show 15,000 shots of the kids. There were others in those people’s lives, too.
As to Mark Bingham: The only possible reference I saw to him being gay was when the plane was about to take off and he called someone—I believe the name was Matt—and left a message telling him he’d made the flight and he’d be arriving at such-and-such a time. I didn’t really get the reference until I re-read this thread. Most people probably would miss it if they didn’t know he was gay.
I didn’t watch this movie, although I was aware of it. I still haven’t decided if I want to see this one currently in production and due out in April.
I was in the news business for nearly 20 years. Tragedy just rolls off my back as a result of overexposure. But this story has stuck with me like no other. I still get emotional every time I think about what those passengers did. Whatever a movie tries to accomplish, I fear that it will cheapen the original deed while attempting to honor it.
I’m wondering if, in 100 years, someone will make a love-story/tragic movie about Sept 11, a la Titanic and Pearl Harbor. For us, we saw the events unfold live. Our unborn grandkids may think it an interesting history factoid, rather than an horror beyond imagining.
