The highly anticipated film is slated to be released on Friday, April 26, 2019.
This is followed by a montage of every Marvel movie, culminating in Vision's statement that "a thing isn't handsome because it lasts" and Doctor Strange's foreboding warning that "we're in the endgame now". Marvel is protecting every detail of Avengers: Endgame much like they protected Avengers: Infinity War.
The newspaper reported that the leak appears to be footage filmed off a large screen inside a screening room - but the origin of the leak is still unknown. Some clips have already been removed or disabled because of copyright infringement.
Avengers: Endgame has Tony Stark (Robert Downey Jr.) reunite with Pepper (Gwyneth Paltrow) and end his feud with Steve Rogers (Chris Evans) after Captain America: Civil War. The source of these spoilers is unclear at this moment, as Marvel has kept a relatively airtight seal on things outside of showing USA press about 10 mins of footage and around 20 mins during South East Asian press junkets. Reuters has not seen the leaked scenes and Disney declined to comment.
Anticipation for Endgame has been building since last year's game-changing Avengers: Infinity War, a billion-dollar blockbuster that saw numerous franchise's beloved superheroes disappear in a genocidal snap of the finger.
Marvel's Infinity Saga began in 2008 and "Endgame" is the 22nd film in the Marvel Cinematic Universe, which features characters such as Iron Man, Captain Marvel and Black Panther. Early reviews will hit theaters earlier in the week.
A week before Avengers: Endgame, the follow-up to Infinity War, gears up to open in cinemas, footage from the film leaked online compelling director duo Joe and Anthony Russo to share an open letter urging fans to not to share spoilers. It circulated under the hashtag #ThanosDemandsYourSilence.
"Avengers: Endgame" arrives in theaters in worldwide territories beginning April 24 and in the USA on April 26.
In turn, are TV audiences going to have to make sure they book their movie tickets opening weekend just so a major movie moment doesn't spoil whatever's about to happen on the Disney+ show they're watching?
