I have no idea why I'm wondering this, but it crossed my mind last night.
When I was actively reading comics, it was back in the 60s & 70s. I haven't read anything put out by Marvel in a couple of decades, but when I was a kid (and at the height of my comic reading), Spidey and DD had kind of a "I know your secret" relationship. Spidey and Johnny Storm also had a kind of a friendship. The thing is, I don't remember Spidey and Tony Stark ever having a friendship of any kind. The way Marvel likes to retcon stuff, though, I wouldn't be surprised if things are vastly different these days as opposed to back then.
So is the relationship between Spidey and Iron Man anything close to the way it was portrayed in the movies?
