It looks like the Marvel cinematographer Trent Opaloch has accidentally revealed the official title for the next Avengers film. Omega Underground saw that Opaloch had included his credits for the film on his website. The latest was for an Avengers: End Game.

Opaloch’s website now simply lists the working title Avengers 4, but Omega Underground has a screenshot of the possible leak. Opaloch has a long-standing relationship with the Russo Brothers, and has worked with them at Marvel for some time, on the films Captain America: The Winter Soldier, Captain America: Civil War, and Avengers: Infinity War.

A number of titles for the Avengers sequel have been circulating, including the one Opaloch listed on his site; however, this is the first time a title has been confirmed in any way. As Omega Underground points out, End Game could still be a placeholder, though the title does seem a bit more official since Opaloch accounted for it in his portfolio.

Either way, we’ll find out soon enough, as the forthcoming Avengers film is slated for release on May 3, 2019. In June, Avengers: Infinity War became only the fourth film in history to gross $2 billion, so it’s clear why the anticipation for the next film is high.
