Box Office: $714.4 million Considering that the Captain America sequel is generally regarded as one of the very best movies in the MCU to date, it's easy to forget that, while it improved massively on the original's underwhelming $370.6 million pull, it still ended up miles away from the billion-plus grosses of Iron Man 3 and both Avengers films. That's right, Deadpool didn't just crush easy MCU targets like Ant-Man and Thor: The Dark World, but it also took on one of the MCU's key players and won. Considering we're talking about a 2014 Captain America movie rather than something more distant and low-key, it was ridiculously unexpected that Deadpool could come out on top.
