Touching! "I love you 3000 times" in "Avengers 4" came from Downey's own child

In Avengers 4, before Iron Man coaxed his daughter Morgan to sleep, her words "I love you three thousand" became a classic line that moved countless audiences. Directors the Russo brothers recently revealed in an interview that this line came from Robert Downey Jr.'s own child.

Robert Downey Jr. has three children, but director Anthony Russo can't remember which child said it. He said: "Robert's own child once said to him: I love you three thousand. We told the screenwriter this story, and it finally became a line in the script... This can also best reflect: What Robert brought to the role of Iron Man."

"Avengers 4" screenwriters Christopher Markus and Stephen McFeely also added in an interview: The original dialogue was "I love you tons (I love you very much)" - "I love you tons (I love you very much)", and Downey said that his children would say to him "I love you three thousand", so they changed Morgan's line to this sentence.
