With Avengers: Infinity War demolishing box-office records with the same speed and efficiency with which it destroyed rumors and theories, fans have begun to turn their attention to the 2019 sequel, and its actual title. We already know it won't be announced for quite a while and that it may not live up to such high expectations, but we're also starting to get an idea of what Avengers 4's title is not.

Characterizing it as "My favorite wrong theory about Avengers 4," Marvel Studios President Kevin Feige recently shot down the idea that the film will be called Avengers: Infinity Gauntlet, a nod to the 1991 Marvel Comics miniseries that inspired Infinity War. Now co-director Joe Russo has dismissed another popular title theory with a comic book connection. Well, kind of.

Although the Russo brothers contend they haven't seen anyone correctly guess the title of Avengers 4, Joe Russo told ComicBook.com that Avengers: Forever might be the closest yet. "The actual title is The Avengers: Almost Forever," he joked.

Avengers: Forever is reference to the 1998-1999 Marvel miniseries (without the colon) by Kurt Busiek, Roger Stern, Carlos Pacheco and Jesus Merino, which brought together Avengers from across time -- Captain America, Hawkeye, The Wasp and Captain Marvel, among them -- to battle the threat of Immortus. The premise seemed to match up nicely with what little we know about Avengers 4, which appears to employ time travel (or BARF technology, or flashbacks), making Avengers: Forever one of the more plausible title theories.

Alas, that, too, is now relegated to the ash heap, leaving us to parse what Joe Russo means by the title being the closest guess yet. Of course, maybe he means Avengers: Forever is 50 percent correct; after all, it almost certainly has "Avengers" in the name.

Directed by Joe and Anthony Russo, Avengers: Infinity War stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Anthony Mackie, Paul Rudd, Elizabeth Olsen, Tom Holland, Benedict Cumberbatch, Chadwick Boseman, Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Vin Diesel, Tom Hiddleston, and Josh Brolin. The film is out in theaters now.
