A new report suggests that child actor Harry Keener, would be likely replacing Robert Downey Jr. in Iron Man 4.

Christian Today speculates that Keener will stepping in as Downey Jr. has most likely exited the franchise.

In a recent interview, Downey Jr., suggested having to drop Iron Man 4 for his upcoming movieCaptain America 3: Civil War.

Speaking to Empire magazine, the actor talked about how Civil War might not have come to be, had he gone ahead with Iron Man 4.

"They said to me, 'If we have you, we can do this, or Cap 3 has to be something else.' It's nice to feel needed. And at this point it's about helping each other, too," he said. "I look at it as a competition and I go, 'Wow, maybe if these two franchises teamed up and I can take even a lesser position, with people I like and directors I respect, maybe we can keep things bumping along.'"

In fact, recent reports are setting off the rumor that a young child might be the main star in Iron Man 4.

Air Herald believes that the child who assists Stark in the third movie, Harley Keener, might take over the mantle of the Iron Man.

Although this seems unlikely, as the actor is most likely reprising his role in the movie and seems to be leaning toward making it work out. During an appearance on the Ellen Show, last year, he strongly hinted at the fact that he would be coming back.

"I know there's going to be a bunch more Marvel movies," he said. 

"And they have big ideas of how to do it best and we're in the middle of negotiation..."  Ellen asked him, "So, yes?"

To which Downey responded in the affirmative: "Okay, yes!"

In another interaction during a Reddit AMA, the actor revealed that we would have more information about the movie in the near future.

"Sooner than later the Marvel Roster will be made public and all questions will be answered."

But it has been a while and we are still waiting for the big public announcement.
