The title, Endgame, is a reference to Doctor Strange’s (Benedict Cumberbatch) line to Tony Stark, “We’re in the endgame” now in Infinity War. "Endgame" also calls back to Stark’s line from Avengers: Age of Ultron (2015): “That up there? That’s the endgame.” While Age of Ultron and Infinity War both borrowed their titles from popular comic book runs, Avengers 4 is breaking the mold with its title.

Infinity War directors Anthony and Joe Russo return for the next Avengers installment, as do screenwriters Christopher Markus and Stephen McFeely.

Joe Russo revealed Nov. 8 that though the film is still in the editing process, the current runtime for the next Avengers movie is three hours. If that holds, that would make it the longest Marvel Studios movie yet (Infinity War currently holds the record with a length of two hours, forty minutes). The upcoming Avengers movie wrapped in October.

Avengers: Infinity War is Marvel Studio's highest grossing movie ever. It earned more than $2 billion globally. The next Avengers movie is expected to be the swan song for several MCU members, notably Chris Evans. Next up, Marvel studios has Captain Marvel due out March 8 and which got a new trailer Dec. 3. It will follow the next Avengers movie Spider-Man: Far From Home July 5, 2019.

Avengers: Endgame will be released April 26, 2019.
