The X-Men joining the Marvel Cinematic Universe is still just a distant hope for fans, but, it turns out there were plans to include them and Spider-Man way back in the beginning of the MCU.
After being presented with the first-ever Stan Lee World Builder Award at the Saturn Awards, Marvel Studios President Kevin Feige revealed a deleted post-credits scene from Iron Man that shows Nick Fury (Samuel L. Jackson) referencing both Spider-Man and the X-Men without actually naming the (at the time) non-Marvel properties.
“We pulled some things out of that vault that we said, ‘We’ll never show this to anybody, put it away,’” Feige says about the deleted scene, according to Entertainment Weekly. “We’re bringing them out, we’re putting them on this disc, and I’m about to show you a deleted scene that has never been seen by anyone before right now.”
The clip begins when Fury approaches Tony Stark (Robert Downy Jr.) at the very end of Iron Man, the first MCU film, talking about the Avenger Initiative — just like in the actual post-credits scene that made it onto the movie. But this alternate scene sees Fury talk about “gamma accidents, radioactive bug bites and assorted mutants” before complaining about how he has to “deal with a spoiled brat who doesn’t play well with others and wants to keep all his toys to himself,” aka Tony.
It’s a short scene but one with huge implications.
Feige also revealed that this scene along with much more teased material will be released as bonus features on the upcoming Infinity Saga DVD box set, so it sounds like there’s a lot more where this came from.
