According to Spider-Man actor Tom Holland, the scene of Tony Stark's death in Avengers: Endgame featured "no real script." Moments after Stark performs the final snap and delivers his epic "I am Iron Man" line, he is met by War Machine (Don Cheadle) and Spider-Man. While Parker seemed to hope his mentor would survive, the inevitable happens after Pepper Potts (Gwyneth Paltrow) tells Stark that he can "rest now."
During a press tour for Spider-Man: Far From Home, Holland described the freedom Marvel gave the actors for Iron Man's final scene. "It was interesting because, when we shot that scene with Robert there was no real script, at all," he told PINKVILLA. "It was just Kevin Feige, the two Russo brothers, myself, Robert Downey Jr., Gwyneth Paltrow and Don Cheadle. They kinda brought us to set, they kind of told us what was gonna happen, or what they wanted to happen and then we sort of just improvised if I can remember correctly."
Downey came up with the idea that Iron Man couldn't speak during his last moments. The actor is known for bringing his improvisational skills to Marvel Cinematic Universe films and even helped re-write much of the first Iron Man film.
