Ever since the MCU kicked off in 2008 with Iron Man, fans have come to expect end credits scenes in Marvel movies, to help set up what's coming down the road. These scenes can serve a few purposes, either to add a fun Easter Egg, like the surprise addition of Howard the Duck in Guardians of the Galaxy, or to set up one of the studio's future movies. Captain America: Civil War will surely continue this tradition, but, naturally, we have no clue what directors Joe Russo and Anthony Russo have planned quite yet. The filmmakers recently spoke with Forbes, where Joe Russo teases that there many be upwards of three end credits scenes, which would be unprecedented for an MCU movie. Here's what he had to say, without revealing what these scenes would showcase.

"We can't say who is going to be in it, but we can say that there certainly could be one, or two, maybe three. We can confirm that you should stay sat in your seats when the movie is done."

Over the past few months and years, several rumors have surfaced regarding Captain America: Civil War, but one of the most recent unconfirmed reports was actually proven true. Shortly before the release of the second trailer, there had been reports that this footage will give us our first look at the new Spider-Man, played by Tom Holland. Some had thought that we wouldn't see Spidey until the movie hit theaters on May 6, but thankfully we got our first look at the web-slinger in the trailer's final shot. The filmmakers revealed that they had always planned on revealing this iconic character in one of the trailers. Here's what Joe Russo had to say about their plans for Spidey's big reveal.

"We always intended to. He was my favorite character growing up, I still have my collection of comics in my closet so it was a dream come true for us to be able to have Spidey in the movie and interpret him as a character so we couldn't be more excited and we wanted to share that with everybody else. We thought it was a great way to reveal him. I think people are going to be happy with him in the movie, he's got a very interesting role in it."

Marvel confirmed in February of 2015 that they had finally struck a deal with Sony Pictures, allowing Spider-Man to debut in the Marvel Cinematic Universe in one movie, before moving on to the Spider-Man reboot, jointly produced by Marvel and Sony, which is set for release on July 7, 2017. While it was never specifically stated what movie he'd debut in, many assumed it would be Captain America: Civil War, since the character is featured in the Civil War comics. Anthony Russo revealed that the deal was rather complicated to work out.

"Also I think it was a little bit of a correction because it was a very complicated deal that Sony had to work out with Marvel Studios and Disney in order to make that work. We were very quiet about Spider-Man's involvement in the movie for much longer than we would have been. We were artificially silent on the character because it was such a sensitive business deal still being worked out even while we were shooting. We went through a very thorough casting process, we tested Tom Holland vigorously with Chris Evans and Robert Downey Jr., we screen tested him along with several other actors, it was a very intense part of making Captain America: Civil War because he was an important part of the movie to us. Finally it's all secure and we're at a place where we can present him even in just a small taste."

When we first saw Spidey in the trailer, he appears after Tony Stark (Robert Downey Jr.) yells out "Underoos". After stealing Cap's shield with his web shooters and restraining his hands, Spidey leaps into frame, holding the shield before introducing himself with, "Hey everyone." This scene not only gave us our first look at the wall-crawler, but it also revealed that he's fighting for Team Iron Man. While we still don't know how large or small his role is in the story, Anthony Russo teased that Peter Parker has a "fun" role because he's coming into this battle completely fresh.

"I'll say this, part of the fun of Spider-Man is that this film is basically a war amongst the Avengers and Spidey does not have the baggage that all these other characters have. He enters the story after the conflict that is happening between the Avengers and that gives him a very unique place in the story."

Captain America: Civil War kicks off Marvel's Phase Three, and shortly after that movie hits theaters, the directors will then get to work on Avengers: Infinity War Part I and Avengers: Infinity War - Part II. The filmmakers are set to direct from a script by Christopher Markus and Stephen McFeely, and the directors recently teased there could be upwards of 67 characters that appear in the two-part movie. Joe Russo says that there will be new characters introduced in this adventure, along with plenty of your old favorites.

"There are New characters that are going to appear in Avengers: Infinity War. It's a big sprawling ambitious movie, it's about as ambitious as movies get and it should be, and the title alone indicates that there will be an incredible scope to it."

Although Inhumans (July 12, 2019) will officially be the last movie in Phase Three, it has been said in the past that Avengers: Infinity War - Part II brings to an end a big part of the MCU. There has been speculation that a number of characters may be killed off to pave the way for new additions in Phase Four, but naturally nothing has been confirmed. Anthony Russo teased that Avengers: Infinity War - Part II does close out part of the MCU, although he wouldn't offer too many details.

"It is intended to be the entire culmination of the Marvel cinematic universe and, in many ways, the end to that part of it. But we don't even have the first draft in on that script yet; we're still in the outline phase. It's hard not to talk about it too specifically now only because of spoilers but also because we're still figuring it out."

Avengers: Infinity War Part I and Avengers: Infinity War - Part II will start shooting in late 2016, during a rumored nine-month shoot that will encompass both movies. Hopefully we'll get some more details on the story before production started, but fans should get a good idea of how this Phase will be shaped when Captain America: Civil War hits theaters on May 6. What do you think about these new details?
