15 Predictions For 2015's Biggest Movies

14. Avengers: Age Of Ultron Will Be Robert Downey Jr's Last Iron Man Movie

Now, we all know that Robert Downey Jr. has been signed for The Avengers 3, though often studios will sign actors for more projects than they reasonably foresee for insurance purposes. Much discussion has already been made about the role of Iron Man potentially being recast in the near-future, due to both Downey's age (he will be 50 by the time Age of Ultron comes out), and the fact that he's made it clear he doesn't want to do the role forever. Downey also finished filming his part in Age of Ultron several weeks ago (much earlier than most of the cast) and referred to himself as "unemployed", which has caused some online to suspect that Tony Stark may even be killed off in the movie. While we consider this unlikely when the character is so lucrative, yet with no Iron Man 4 in sight, it seems quite possible that Downey will throw in the towel with this movie, as by the time The Avengers 3 starts filming, he will likely be 52 or 53. On this one, we sure hope we're wrong, because for starters, he doesn't look his age, but we'll have to wait and see...
