I can't imagine you missed something .
One more, in the police van after Kay gets picked up in the gay bar. I'm sure there are more.
The hand grab scene: you are right, it's very erotic and I'm still wondering how two hetero actors can do this. Even for a male/female couple it would be difficult to create such a sexual tension. I think it's a combination of great acting and real life chemistry (that chemistry must be real, you can't fool viewers with that). And I know we spoke about this before, but I'm still not 100% convinced that there is really no attraction at all between Hanno/Max. I mean, in an interview they spoke about "a thin line between gay/straight". So wouldn't it be possible that a person is straight but with one toe or foot over that line just for a certain same gender person (or more persons)? Lousy explanation but I hope you understand what I mean.
Non-verbal language can be very strong, is it even possible that a certain atmosphere between two people can be acted when it's not real?
As for the thin line, and maybe an attraction between Hanno & Max, I have no opinion on that - could be, I suppose. I'm sure you see more articles about them than I do.
When Brokeback came out, there were whole websites dedicated to discussing the sexual preferences of the two stars, especially Jake. The paps (and fans) were ruthless and kept Jake in the news about it, always questioning it when Jake was out with a guy friend, and constantly saying he was "dating" friends he had known and hung out with for years. Of course it could be true, but the speculation about Jake was sometimes cruel and unnecessary (not from an actual interview, as you posted above), and I had no opinion about him, either.
I haven't seen any news about Hanno or Max, not even if they're dating women, let alone men. I think the German press is either ahead of the curve and don't care, or has better things to do.
I guess if someone has a toe or foot over the line, they'd be bi, and that's a whole other thing to deal with. Some people don't even think it's a valid sexual preference (not sure if that's the way to put it.) Maybe we can get some input/opinions from Vincent or others, if they stop by.
