Anthony Russo: To their credit, we have never gotten a time mandate from them [Disney].
Joe Russo: I’ll say it could easily be a three-hour film, but I think that we’re very hard on the material, we like it to play at a certain pace. I’m sure that we’ll squeeze it.
Anthony Russo: We have a whole year of work left on that movie.
Joe Russo: I do think it will be longer than Avengers 3.
根據導演所說，目前《Avengers 4》還在很初步的剪輯期間，但已經是眾多 Marvel 電影中最長的初剪，不過目前還有一整年的工作要跟進，所以還未能確認電影的最終長度，然而作為一個時代的終結，《Avengers 4》以更長的時間去交待絕對合理。
