You’re not going to watch the Battle of New York the same way anymore!
The battle for New York in the movie The Avengers marked a turning point in the MCU. It indeed represents the culmination of plans from the studios that introduced the original six Avengers since 2008. This epic and heroic sequence has, however, a little lost in credibility because of a cut scene from the film Avengers Endgame (that you can find just here). As the remaining heroes view footage of the Battle of New York City, Rocket is interested in the conditions of this fight and asks them how long they fought the Chitauri. What Natasha Romanoff responds to for two or three hours, which does not fail to amaze the Guardian of the Galaxy.
