The Marvel Cinematic Universe's own Hulk has taken to social media to mark the Fourth of July, with an appropriate image from Avengers: Endgame.Posting on Twitter, Mark Ruffalo wished everyone a happy Independence Day and accompanied his seasonal greeting with a screenshot from Avengers: Endgame, showing off Captain America and, as both Ant-Man and Steve Rogers called it, "America's ass."
The gag began in the second act of Avengers: Endgame, when Tony Stark commented on Cap's costume and how it did nothing for the super soldier's backside, causing Ant-Man to reassure the First Avenger, "As far as I'm concerned, that's America's ass," something Cap himself would agree with after seeing an alternate version of himself.
Avengers: Endgame flung Earth's mightiest heroes into various points of the past on a mission to collect the Infinity Stones. The film introduced alternate versions of familiar characters, bringing some back from the dead and allowing others to transform. One of the biggest changes was the passing of the mantle of Captain America from Steve Rogers to his friend, Sam Wilson. The monumental ensemble film concluded Phase 3 of the MCU and was a critical and financial success, widely praised by critics and grossing approximately $2.7 billion worldwide.
