1. Robert Downey Jr. Is Iron Man
It might sound like a foregone conclusion, but it's been widely reported that Robert Downey Jr's contract for the Iron Man franchise has expired as of the third film. Though it's presumed that he will sign a new deal that will include at least The Avengers 2 and probably a fourth Iron Man film, there have been hints that Downey may not make it for a fourth film, and Marvel producer Kevin Feige has stated that they will proceed without Downey if necessary, which of course means re-casting Tony Stark. Frankly, I can't think of a more horrible idea. Downey has made the role so inimitably his own that anyone else trying to take the mantle would just not be accepted by fans. Simply, no Downey, no sale, no Iron Man. Get him on board or don't bother (maybe draft in Spider-Man instead?) What do you want to see from Iron Man 4? Let us know in the comments below.
