After the devastating events of Avengers: Infinity War (2018), the universe is in ruins. With the help of remaining allies, the Avengers assemble once more in order to undo Thanos' actions and restore order to the universe.
IMDb has 'Avengers' and the whole Marvel Cinematic Universe covered with all the latest clips, interviews, and in-depth info.
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.
Tell my family I love them.
Natasha Romanoff: You tell them yourself.
When 2014 Thanos arrives in the present day (thanks to 2014 Nebula) this would create a time paradox - as Thanos no longer exists in the past the events of Avengers: Infinity War would not come to pass. Thanos would not be around to collect the Infinity Stones and the Snap would not happen. Akin to the 'Grandfather Paradox' The other explanation for this is the events of Endgame create a slightly alternate timeline, whereby the events of the MCU remain unchanged and cannon while a new alternative timeline has been created in another reality whereby Thanos disappears from events in 2014 and the Infinity War storyline does not take place - similar to the conversation between Bruce Banner and The Ancient One.
There are no opening credits aside from the movie's title.
