RDJ's only signed on for Avengers 2 and 3, he keeps asking for more and more money, he's getting older, and eventually he'll have to be replaced. So I just had an idea how they could handle the transition in the movies and introduce us to the new actor. Avengers 3: In the final battle with Thanos and the Infinity Gauntlet. Tony gets killed by either the Time Gem (aged to death) or the Soul Gem (soul taken), and his body is damaged. After Thanos' defeat, there is celebration and mourning, and Tony is given a funeral. Mid-Credits Scene: Before it's taken away, someone uses the Reality Gem to wish him back. Tony's body is restored, and the new Tony opens his eyes (maybe even gets up and asks for a drink). Iron Man 4 could then open Phase 4 and deal with the repercussions of his resurrection. Thoughts?
