With "Captain America: Civil War" on the eve of its release here in the U.S., discussion has already shifted ahead to the next major Marvel crossover film(s), the tentatively-titled "Avengers: Infinity War Part 1 & 2." The Russo brothers, who are directing both films, have now confirmed that the feature is indeed shooting in November -- with Part 1 and 2 shooting back-to-back -- and that the scripts are well underway, as they'd been working on them since "Civil War's" post-production.

In an interview with Deadline, Joe addressed the duo's progress on "Infinity War," saying, "We already started [the scripts], a couple months ago. We had to. We start shooting in November, two movies back to back. So we need two scripts ASAP, and we probably started working on them six months ago."

When asked if they took advantage of the actors during "Civil War" filming for "Infinity War" work, Anthony said that they did not -- but did reveal that they worked alongside co-writers Christopher Markus and Stephen McFeely on the scripts throughout editing: "...Just story, with Markus and McFeely, the writers. Hardcore conversations. As soon as we got into post on this movie, we gave ourselves a few weeks to transition and then we spent half days with the writers, and half in the edit room, for months. We'll get the first draft of both scripts when this movie opens."
