Avengers: Endgame has continued to smash box office records. One of which included that it’s the #1 Box Office Opening Of All Time.
The Endgame Directors, Joe and Anthony Russo, also have revealed what the original title for the film was. Much to the surprise of the fans, it wasn’t Avengers: Annihilation at all.
It was actually Avengers: Infinity Gauntlet. The Russos didn’t explain why the film’s title had changed, but there was probably a good reason for it.
But, this isn’t the first time we’ve heard about Endgame’s original title being Infinity Gauntlet. Gamora actress Zoe Saldana did reveal the title in 2017 during an interview for Guardians Of The Galaxy Vol. 2.
It is still unknown why the title got changed to Endgame, but it seems like Avengers: Endgame was a better title then Avengers: Infinity Gauntlet.
