Captain America 3 will start filming in Atlanta next spring.

The sequel to Captain America 2 and a continuation of the storyline from Avengers: Age of Ultron will begin filming in and around Atlanta, Georgia in April 2015, revealed Collider recently.

The first Captain America film was shot in the United Kingdom, New York, and Los Angeles while the second was mostly filmed in Ohio and LA.

Captain America 3 is set to hit theaters on , 2016.

Co-director Anthony Russo said that there will be additional locations for Captain America 3.

“It’s not an all-Atlanta shoot, it’s a lot of stage work in Atlanta. There’s other locations that are also involved that I don’t think we can get into,” he said.

Anthony and co-director Joe Russo have been revealing new details about the upcoming addition to the Marvel universe.

They fielded a question about Hawkeye (Jeremy Renner) possibly being in Captain America 3.

“I was gonna say Renner might be misremembering because he was supposed to be in Cap 2 but we couldn’t make his schedule work [laughs]. Maybe that’s what he’s talking about. It’s certainly difficult. Everyone involved in these films are all movie stars, and a lot of that has to do with the fact that they’re in Marvel movies, so all of their schedules are booked up. It does become very complicated,” Joe said.

“There were iterations of Cap 2 that had Hawkeye and Widow in it, there was an iteration that had just Widow in it and there was an iteration that had nobody in it. You explore all of those iterations until you settle on what you think is the most potent or most powerful. And sometimes scheduling issues assist in that decision making process.”

Joe also revealed that a large part of Captain America 3 will revolve around the Winter Soldier.

“What’s left to explore obviously is the personality of the character, much the way that Brubaker’s run did after Winter Solider regained a semblance of his past. Philosophical questions that we would want to deal with in Cap 2 would be, you know, is he redeemable? Is he the worst assassin we’ve ever seen or is he the longest suffering POW? Where does he live now? Does he ever regain his memories?”

Joe teased to Crave Online about the plot centering around a big idea.

“The big thing we knew we had to deal with in Cap 2 was the fall of Hydra. Similarly there is a very, very big idea at the center of Cap 3,” he said.

“But how we get there is all up to us. And I think why Marvel has been so successful is because it’s been such a clear plan, that everything is interconnected and they’re building emotional capital with each movie that you can then trade off of in the next film.”

Asked about the villain, the main cast members, and other parts of the major plan, Joe added:

“All that stuff is open for interpretation. Usually it’s just one big idea that alters the universe as a whole in some way, that has interconnectedness that he’s grabbed on to. That’s the case with Cap 3, but as far as villain and story arc and tone, all that stuff is left up to us.”

And the Russos said that they’ve been working with Marvel president Kevin Feige on the title for about a decade, and they will reveal the title soon publicly.

Robert Downey Jr. to Join ‘Captain America 3′ (EXCLUSIVE)

Robert Downey Jr. is on the verge of signing on to “Captain America 3,” a move that would bring the Civil War storyline from Marvel’s comicbooks to the bigscreen and trigger the start of a new phase of movies from Marvel Studios.

The actor is in final negotiations to play billionaire Tony Stark in the third installment, which is slated to begin production in the Spring for a May 6, 2016 release. Downey is already set to suit up as Iron Man for next year’s “The Avengers: Age of Ultron” and “The Avengers 3.”

The deal is significant for the Marvel cinematic universe considering the plot will pit Stark against Captain America’s alter-ego Steve Rogers, played by Chris Evans, as they feud over the Superhero Registration Act, which forces anyone with superhuman abilities to reveal their identities to the U.S. government and agree to act as a police force for the authorities.

Stark supports the program, but Rogers does not, saying it threatens civil liberties, causing sides to be taken and Rogers, among others, to go on the run to avoid arrest. The moral question and battle with his Avengers teammate essentially makes Stark a villain of sorts in “Captain America 3,” providing Downey with a meaty role he could play out into future Marvel films, including a fourth “Avengers.”

Marvel on Monday announced plans to reboot the Civil War comicbook miniseries in 2015, which will help introduce the story to new readers leading up to “Captain America 3.” The first crossover over Marvel’s biggest characters, including Spider-Man, was published in 2006.

But the deal for Downey to return as Iron Man almost didn’t happen.

Originally, Marvel wanted to hire Downey for a small role, which would have required just three weeks of work. But Downey wanted Stark to have a more substantial role in the film’s plot, which would give him more screen time and naturally a bigger payday. This angered Marvel Entertainment chief Ike Perlmutter, who ordered the screenwriters to write Iron Man out of the script entirely, according to sources with knowledge of the situation.

Even though the deal appeared dead, Marvel Studios president Kevin Feige and Downey’s reps at CAA continued talks in hopes of working out their issues. Feige was bent on executing his grand vision for extending the life of the Marvel characters over many years.

The executive needed his boss to see the big picture, considering the introduction of the Civil War story is seen as a way to drive the plots of sequels and new franchises for the next seven years, given the dramatic possibilities it offers for future films. The fallout from the government and Stark’s actions would factor into a new “Avengers 4″ film and beyond that will assemble new characters being introduced like Ant-Man and Doctor Strange, among others, in their own movies.

Downey, who earned $50 million for “The Avengers” alone, will collect around $40 million plus backend participation for “Captain America 3,” said sources, and will get an additional payout if “Captain America 3″ outperforms “Captain America: The Winter Soldier’s” $714 million worldwide haul. Since the actor did not appear in the first two “Captain America” films, the thinking is that if the third installment surpasses the last movie, its success could be attributed to Downey.

It’s also worth noting that Evans is clearly a bigger star now, evidenced by the fact that “Captain America: The Winter Soldier” grossed nearly twice as much as “The First Avenger’s”” $371 million in 2011.

Marvel still could have worked around Downey if need be. With the studio having already reworked plots from the comicbooks to fit its bigscreen agenda, it’s certainly feasible that Stark could have been turned into a different character to butt heads with Captain America — the Incredible Hulk’s Bruce Banner, for example. Another option could have been dropping the Civil War plot entirely, which would have required major rewrites.

Downey already has been open about wanting to remain in Marvel’s cinematic universe beyond his current contract that expires after the third “Avengers.” In early September, Downey told Variety in Toronto that currently “there is no plan for a fourth ‘Iron Man.'”

Yet Downey also has been wanting to play a larger role in future films as a way to remain creatively involved and close to his fanbase that would undoubtedly come out to see his non-Marvel movies. However, those fans didn’t show up in droves this past weekend to the actor’s latest picture “The Judge,” which debuted with just $13.3 million.

As for the future of Marvel movies, the Disney-owned studio already has 11 releases dated through 2019, including next summer’s “Avengers: Age of Ultron” and “Ant-Man.”

Anthony and Joe Russo, who directed “Captain America: The Winter Soldier,” will return to helm “Captain America 3.” The brothers are working on the script with Christopher Markus and Stephen McFeely.

While Frank Grillo is expected to return as the villain Crossbones, Anthony Russo told Movies.com last month, “I can’t divulge who is going to be in the film, but I think fans are going to freak out when they hear about it,” clearly hinting at Downey being in the next sequel.

While Downey was instrumental in getting Marvel’s film franchises off the ground with the first “Iron Man” in 2008, the studio has since become a brand strong enough to launch titles that have little built-in audience awareness or major stars doing the heavy lifting — as evidenced by this summer’s mega-hit “Guardians of the Galaxy.” That film earned $687 million worldwide, surpassing “Iron Man 2.”

Marvel has long been known as a tough negotiator — and by some accounts cheap — but the studio hasn’t shied away from giving Downey what he’s asked for in the past. He’s reaped between $250 million and $300 million for the “Iron Man” trilogy, his role in “The Avengers” films, and a brief appearance in “The Incredible Hulk,” according to knowledgeable sources.

Now with “Captain America 3,” it doesn’t look like Downey is ready to hang up Iron Man’s suit anytime soon.

Marvel and CAA declined to comment.
