When Marvel made the announcement about "Captain America: Civil War," that pretty much confirmed the rumors and speculations that have been going around for months about what the third movie will be. Ever since, there's been a lackluster of updates of Captain Steve Rogers' third movie. 

But low and behold, out of the blue, Iron Man himself, Robert Downey Jr. posted a tease of "Civil War" on his Facebook page. He posted a photo of Captain America riding on Iron Man's back. What could this mean though? 

Guessing from the recent posts that Downey has made, it's safe to say that it's just a complete tease or a joke, just to keep things entertaining. After all, the "Civil War's" plot will pit the Captain and Iron Man against each other due to the Superhero Registration Act. 

It is very sad to hear that the Avengers may split sides on this one. The Superhero Registration Act is proposed by the government and it mandates all superheroes to sign up so they can be monitored by the government. Captain America doesn't support it, while Iron Man does. All the other superheroes pick their sides as well, and all this leads to a war between two opposing sides. 

However, there have been rumors that Captain Steve Rogers will meet is demise in the third sequel, too. How true could this be? Frank Grillo, who is set to play Brock Rumlow a.k.a. Crossbones, sort of spilled the ending of "Captain America: Civil War." 

In an interview with Collider, Grillo said, "I have a multi-contract deal with Marvel. The movie was an origin film for that character. If you know the comic, he has a significant presence. So, knock (on) wood. With Marvel, you can't say very much, but I'm cautiously optimistic that we'll have some fun, in the next few Marvel movies." 

While Grillo may have not said anything outright, his statement revealed a lot about what might happen to Captain America. For comic readers, it is known that Crossbones will be the one to kill the Captain with his bullets. Additionally, the rumors of Chris Evans retiring certainly feeds this rumor further. 

"Captain America: Civil War" will hit theaters on May 6, 2016.
