10. A Famous Comic Book Writer Wrote The After-Credits Scene
When Marvel released Iron Man and The Incredible Hulk in 2008, their plan was to build up to The Avengers. That movie was originally set to be released in 2011 and would have been written by Zak Penn. While details about his take on the team have never been revealed, it's thought that it would have focused on the team taking down The Hulk, and Iron Man's Jon Favreau was heavily rumoured to be the one who would direct the superhero ensemble. Despite all of that, Iron Man's after-credits scene featuring Nick Fury telling Tony Stark about the "Avengers Initiative" was originally conceived as just a fun moment for comic book fans. Kevin Feige and Jon Favreau enlisted the help of Ultimate Spider-Man writer Brian Michael Bendis to write this scene, and he put together three pages of dialogue for the surprise exchange between Stark and the Director of S.H.I.E.L.D. The best bits were then chosen, and the scene was shot in secret with only a skeleton crew. Even so, it still ended up leaking. While its existence may have now been common knowledge, Marvel did their best to surprise fans by not unveiling the history making credits scene until Iron Man's premiere.
