Joss Whedon claimed that juggling all the characters in the film was "a nightmare": "They're very disparate characters. The joy of The Avengers is they really don't belong in the same room. It's not like the X-Men, who are all tortured by the same thing, and have similar costumes. These guys are just all over the place, and so it's tough." He was so exhausted with working on this film that he decided not to direct Avengers: Infinity War (2018) and Avengers: Endgame (2019).
