Trivia: The first MCU movie to feature the word "fuck", when Quill tells Nebula to "open the fucking door", a line that was improvised on-set and kept in because it was so funny. James Gunn anticipated being told to cut it out, but Kevin Feige left it up to Gunn's discretion. Feige said the Russo brothers had a "fuck" in an early cut of Avengers: Endgame, but they "didn't want that to be their legacy, so if you want that to be your legacy, then sure." James Gunn said that just made him even more keen to keep the line in, at which Feige "laughed his ass off."
