Joe Russo has warned that seeing Avengers: Endgame is "required" in order to understand Avengers: Doomsday.
A new version of the 2019 blockbuster, titled Avengers: Endgame Encore - which includes additional footage not seen in the original and a sneak peak at Avengers: Doomsday - is being released in cinemas next month and the director urged fans to buy tickets for a screening, even if they have seen the film before, because it will help "connect the story" ahead of the release of the next instalment of the Marvel Cinematic Universe (MCU) franchise this December.
