8. Iron Man 3 (2013)
Tony Stark gives a conference about integrated circuits at a New Year’s Eve party. After his unfortunate performance, Stark meets Aldrich Kilian who offers him a place in his A.I.M. project, Advanced Idea Mechanics.
When the credits are finished, we see Tony Stark narrating his experience to Bruce Banner. He had fallen asleep and had to explain to Stark that he wasn’t that kind of doctor. We can also see the phrase Tony Stark will be back.
