You may have spotted the latest rumor that the still-untitled Avengers 4 is actually called Avengers: End Game. 

Cinematographer Trent Opaloch recently updated his personal website with a line indicating he's done work on a film titled Avengers: End Game, directed by Joe and Anthony Russo. Opaloch has worked on a number of Marvel Cinematic Universe films, including Captain America: Civil War and Avengers: Infinity War.

End Game itself has been floated as a potential title for the film since before the release of Infinity War, but this is the most solid information to play into that theory yet. While the name itself makes total sense given the events of Avengers: Infinity War, we're not so certain that's going to be the final name of the film.

After all, Avengers 4 co-director Joe Russo said so himself.

In an interview with Uproxx, the Russo Brothers fielded questions about the upcoming sequel, so when the questions came up whether the title of Avengers 4 was spoken at any point in Infinity War, Joe Russo had a simple answer: "No."

If you've seen Infinity War, you'll remember that prior to the "dusting" of Doctor Strange following Thanos' iconic snap, the good Doctor mutters the words, "We're in the end game now." And while that being the title of the next film would be a solid enough callback, Russo's comments that the title wasn't spoken in Infinity War lead us to believe that End Game won't be the final title of Avengers 4. 

Then there's comments from Marvel Studios President Kevin Feige, who is consistently amused by fan theories and speculation on what the title of the next film could be. Feige and the Russos have shot down a number of potential titles in the last few months, from Infinity Gauntlet, referencing the 1991 Marvel event, to Avengers: Forever, a late-90s miniseries that saw the Avengers take on Immortus.

Bits of information have supported both of those theories, what with flashbacks and time travel of sorts seemingly being a part of Avengers 4, but Marvel Studios was quick to quell those rumors. But Joe Russo also said that Avengers: Forever might be the closest guess yet.

“The actual title is The Avengers: Almost Forever,” he joked, while talking with ComicBook.com.

So if Avengers: Forever is the closest guess yet, does that line up with End Game as a potential title for the film? Not really. End Game implies that everything is, well, ending, and that the events put into motion as early as 2008's Iron Man could finally be reaching a climax.

End Game is, by definition, the opposite of Forever, leading us to believe that we still have no idea what Avengers 4 will actually be called. And with the promotional period set to ramp up for Captain Marvel in the next few months, there's a chance we won't know what the Infinity War sequel will be called until the end of 2018 at the earliest.

For now, we'll just have to sit tight and keep an ear to the speculation. After all, whether it's the title or not, Doctor Strange's words ring true: "We're in the end game now."
