So one has to imagine that, at some point or another, Marvel will pursue another Iron Man movie, with or without Robert Downey Jr. If that day ever comes, maybe we’ll hear Neill Blomkamp’s name thrown into the mix.
For one, there is no indication that Marvel is going to do Iron Man 4, or an Iron Man reboot, anytime soon.
If Marvel ever decides to make Iron Man 4, they have a solid director who would be happy to take the job.
Also, let’s not forget that Chappie was far from a success and that a studio like Marvel would possibly have some hesitation in giving him the keys to the Iron Man franchise.
