Several rumors have been going around lately about the supposed next installment of "Iron Man," which talks about the movie's next release, Downey's replacement, and who's going to replace him.

According to a report by Parent Herald, Robert Downey Jr., in an interview with Ellen DeGeneres, confirmed that there will indeed be an "Iron Man 4." At first, Downey skirted around the issue by talking about how Marvel has great ideas for new movies and that they're in the middle of negotiations. Ellen, not letting him off easily, prodded him more until he finally said, "Ok, yes."

The site also said that the movie is planned to be released on 2019, but the exact date for the movie has yet to be confirmed.

Another rumor that is gaining a lot of ground recently is about Downey being replaced for "Iron Man 4," and it's being attributed his alleged demand for higher pay. 

It has been reported that production for "Iron Man 4" is currently being held because Marvel execs and Downey still haven't come into agreement regarding his request for a fatter paycheck. Even if it were true, could this really be reason enough to replace him? And with whom?

Movie Pilot points to a familiar face that has also been seen recently in "Iron Man 3," the kid who played the role of Harley Keener, Ty Simpkins.

The site mentioned that the rumor came from a post in Bamsmackpow. Nick Tylwalk, who wrote the article, said that since Simpkins was already a part of the previous "Iron Man" movie, he could possibly be the one to take over the title role. Tylwalk even gave his story on how Simpkin could possibly fit the role.

The 13-year old actor, who also starred in "Jurrasic World," would be around 18 years old if he ever gets the title role that is said to be released in 2019. Given his previous roles and impressive achievement — he got nominated for Best Performance by a Younger Actor at the Saturn Awards for "Iron Man 3" — some people argue that he could just possibly be in line to play Tony Stark.

Still, all these things remain rumors until someone who has the final say confirms it in the days to come.
