Avengers: Endgame (2019)

Robert Downey Jr. was the only cast member who was entrusted with the entire Avengers 4 Endgame script.

During Avengers 4 Endgame ‘Marvel Studios’ opening sequence, all of the characters that were affected by the events of the Decimation from Avengers: Infinity War (2018) were removed.

Evangeline Lilly and Paul Rudd were filming Ant-Man and the Wasp (2018) and this film at the same time.

Even though Captain Marvel (2019) was released one month before this film, Brie Larson shot her scenes for this movie first.

As they did with the previous film, the Russo Brothers wrote a letter to fans, asking them not to spoil anything about the movie, as part of a viral campaign on the internet. The hashtags were #DontSpoilTheEndgame and #ThanosDemandsYourSilence.

Natalie Portman‘s appearance in the film was created with leftover footage from Thor: The Dark World (2013), and she also did voice-over work for a scene when she is talking in the distance. Although Portman didn’t shoot any new scenes, she attended the film’s premiere.

Avengers: Endgame (2019) became the biggest pre-sale title ever on Fandango and Atom Tickets sites, causing them to crash minutes after the sales were announced. It accomplished this feat in only six hours. Some theaters across the world had so many sold-out showtimes on the opening weekend that Cinemark, Regal, and AMC theaters chose to add new overnight screenings so that they would be working around the clock to accommodate extra shows.

Since his introduction in the Marvel Cinematic universe, Chris Evans has appeared as Steve Rogers/Captain America in one film a year except for 2015 where he appears twice, totaling eleven times.

Robert Downey Jr officially surpassed Hugh Jackman’s record for most appearances in film as the same superhero with 10. He set this record in only 11 years, where as Jackman did it in 17.
