Given his popularity among Marvel superheroes, Spider-Man is likely to get his second and also his third servings in the MCU, that is, if those two films are within the bounds of the agreement between Marvel Studios and Sony Pictures, who holds the right to the web-slinging superhero.
In addition, there are also reports coming out saying that there has been a protracted negotiation happening between Marvel Studios and Robert Downey Jr. with regards to his salary for the possible “Iron Man 4.” Although it seems unlikely to be true considering that Marvel and the actor have yet to start working on the two-part final Avengers movie at this time.
It has been said that the actor is even willing to move on from playing the role of Tony Stark and Iron Man after “Avengers: Infinity War Part 2” so the rumored negotiations about “Iron Man 4” are merely based on hearsays at this juncture.
The same set of rumors is saying that Robert Downey Jr. might be replaced by a younger actor or actress who shall then take on the iron suit and become the next Iron Man. Though given the huge popularity of Robert Downey Jr. as Tony Stark and Iron Man, Marvel Studios would surely be courting huge fan backlash if it proceeds toward such direction.
