The next big battle for the Marvel Cinematic Universe will be Captain America: Civil War, which will hit movie theaters this May. In the meantime, as the Russo brothers near completion on that film, the script for Avengers: Infinity War is starting to come together, although it’s still in the outline stage. The Russo brothers have previously commented that they are looking at 67 characters for inclusion in Infinity War, which has led fans to speculate who would be involved, although at the time it seemed more like an offhand comment. And while 67 still seems like an exaggerated number, it in a recent comment, the directing duo confirmed they do have plans to introduce new characters into the MCU with the two-part Infinity Wars.

In a recent interview, the Russo brothers acknowledged the large scope of the movie, but they weren’t able to give much more in the way of specific information.

“New characters are going to appear in Avengers: Infinity War,” says Joe Russo, one of the two directors of the film. “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 scape and scope to it.”

They went on to explain the reason for such breadth in the movie.

“It is intended to be the entire culmination of the Marvel cinematic universe and, in many ways, the end to that part of it,” adds Anthony Russo. “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 not only because of spoilers but also because we’re still figuring it out.”

With this ominous news, anything still seems possible. Maybe after seeing Captain America: Civil War, we’ll know more about what characters are still around and likely to appear in Avengers: Infinity War when the first part premieres in May of 2018. If they are really doing this movie as a culmination of the MCU, it would seem that the television characters, both from the Netflix shows and Agents of S.H.I.E.L.D. could make an appearance, after all.
