'Captain America 3' Is 'Gonna Be Huge,' Says Robert Downey Jr.

Robert Downey Jr. is reportedly in negotiations to return as Iron Man in Captain America 3. He's obviously clued into Marvel's plans for the rumored Civil War plot of the film, so it is bound to raise eyebrows when he says the film is "gonna be huge."

In an interview with Yahoo Movies about his upcoming film The Judge, Downey was asked about the reports that he would play a big part in Captain America 3.

The actor responded by smiling and coyly stating, "Yeah, that sounds very exciting."

Downey's entire demeanor during this portion of the interview was on the level of someone who can't really answer the questions he is being asked. Marvel is very strict about actors leaking details of its movies, which is what has given rise to an entire industry of entertainment website seeking to uncover those details.

When asked if he can comment on the rumors of Iron Man appearing in Captain America 3, the actor says, "If I do, I'll just regret it." He then added, "It's gonna be huge" before giving a knowing look at the camera and adding "whatever it is."

That "whatever it is" has been a key spark of chatter since the rumors first appeared last week via Variety. Marvel Studios hasn't made it official, as they will likely keep this undercover until they are ready to make the announcement or something even bigger leaks out.

The Civil War story arc was an eight-issue run by Marvel Comics in 2006 and 2007 that included multiple tie-ins from other Marvel series. After a battle between The New Warriors and some villains resulted in the death of over 600 civilians, the Superhuman Registration Act was passed. It required the mandatory registration of anyone with super powers, the reveal of their secret identity, and the "option" to work for S.H.I.E.L.D. as part of a larger police force.

Marvel superheroes came down on either side of the issue, with Iron Man leading the pro-registration side and Captain America leading the anti-registration side. The series served as a political allegory to the Patriot Act much in the same way the Mutant Registration Act in the X-Men comics and movies was an allegory for the 1960s Civil Rights movement. It also served as a mechanism to see heroes duke it out with heroes.

Captain America 3 will be out May 6, 2016. We'll have to get through The Avengers: Age of Ultron on May 1, 2015 first to see how the ramifications from that film lead into the third Captain America film.

How huge do you think Captain America 3 will be? Sound off in the comments below.
