Captain America: Civil War isn't even out yet, and already, fans can't wait to learn more about what comes next. Such is the nature of the cinematic universe that Marvel has created, as moviegoers are always wanting to see a tease of the next big film once the credits roll.

In that case, fans definitely won't want to miss the end of Captain America: Civil War. In a recent interview with Forbes, directors Anthony and Joe Russo opened up about why fans will want to stay glued to their seats, saying the movie could (maybe) include up to three post-credit stringers or Easter eggs.

"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," Joe Russo says. "We can confirm that you should stay sat in your seats when the movie is done."

The directors spent much of the interview discussing Spider-Man's role in the film, as well as the reaction to his costume thus far.

"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," Anthony Russo says. "He enters the story after the conflict that is happening between the Avengers and that gives him a very unique place in the story."

In terms of Spidey's costume, the brothers say that it was the costume they and Kevin Feige loved the most and that they think fans who have been less than enthusiastic about the character's appearance in the film will change their minds when they see the finished product. The brothers also discussed keeping Spider-Man's role in the film secret for so long.

"We were very quiet about Spider-Man's involvement in the movie for much longer than we would have been," Anthony Russo says. "We were artificially silent on the character because it was such a sensitive business deal still being worked out even while we were shooting."

Now that the character is officially a part of the Marvel cinematic universe, one might assume Spider-Man will also be set to appear in the two-part Avengers: Infinity War. The Russo brothers aren't saying whether or not that is the case, but they do say in the interview that the two films will feature numerous never-before-seen characters.

Captain America: Civil War releases on May 6.
