Yeah, but you can read into things all you want as long as you feel the text invites you. At some point, all authors must be detached from what they create; all art must be given the space to breathe and exist outside its intended origins - whatever "authorial intention" means.

(It's interesting the amount of backlash JK Rowling got from fans for outing Dumbledore as a homosexual. In essence, though, she's not right (nor is she wrong), she's just analysing her own work. And I would argue that artists are simply their own first audience.)

This isn't "over-analysing" or "reading too much into things". I don't even claim that Tony is bi-sexual - I'd have to watch the film again to give a more detailed study, and I don't really want to because I don't like it.

Whatever, though, of potential arguments for Tony's sexuality (I won't beat a dead horse), I still think it's extremely interesting that, armed with a massive gun (substituting what?) in the climax , the first words that come out of his mouth are:

"Say hello to my little friend."
