Iron Man and Tony Stark appear to be the busiest Marvel superhero and alter ego, respectively, in the next four years.
Aside from being part of "Avengers: Age of Ultron" due for release on May 1, 2015, and "Captain America: Civil War" on May 6, 2016, Robert Downey Jr. is expected to be casted as Iron Man and alter ego Tony Stark again in "Avengers 3" and the on-again off-again "Iron Man 4."
In the October 7 episode of the "The Ellen DeGeneres Show," Robert Downey Jr. graced the show and said that he is in the middle of a negotiation for "Iron Man 4," reported Coming Soon.net.
When asked point blank by Ellen if his answer means a yes, Downey said: "Okay, yes!"
Before his guest appearance on Ellen, Downey revealed to Variety in a September 7 article that there is no plan for a fourth Iron Man movie.
"There isn't one in the pipe. No. there's no plan for a fourth Iron Man," Downey was quoted by Variety as saying then.
After his guesting on Ellen, Robert Downey Jr. has not opened his mouth about "Iron Man 4."
But Christian Today reports that regardless of a fourth Iron Man movie or not, Tony Stark and Iron Man will be back in at least two confirmed Marvel movies - "Avengers: Age of Ultron" and "Captain America: Civil War." The two Marvel movies will come out in 2015 and 2016, respectively.
If plans are finalized for "Avengers 3," which will have a projected release date of 2018, Iron Man and Tony Stark would be in the big screen at least three times in the next four years.
That leaves Marvel Studios with the year 2017 without Iron Man and Tony Stark in any of its upcoming movies.
And should "Iron Man 4" do come out as official once negotiations between the company and Downey is finalized, then it is likely to hit theatres in 2017, movie experts believe.
In the "Avengers: Age of Ultron," fans have been speculating that Iron Man will have a big fight with the Incredible Hulk, reports Cinema Blend.
The trailer of the movie also shows Iron Man trying to lift's Thor hammer in a comedic moment, cites The Verge.
Meanwhile in "Captain America: Civil War," Tony Stark will clash with Steve Rogers, Captain America's alter ego over the Superhero Registration Act, cites Christian Today.
The report also related that Stark has been tasked to supervise the registration of superheroes, which does not suit Steve Rogers well leading to their confrontation, and eventually, between Iron Man and Captain America.
