<P> McDonagh was inspired to write Three Billboards Outside Ebbing, Missouri after seeing billboards about an unsolved crime while traveling "somewhere down in the Georgia, Florida, Alabama corner". "The rage that put a bunch of billboards like that up was palpable and stayed with me", McDonagh said . Of writing his scenario, McDonagh noted, "once I decided, in my head, that it was a mother, everything fell into place". </P> <P> The character of Mildred was written with Frances McDormand in mind, and likewise the character of Dixon was written specifically for Rockwell . McDormand initially felt that she was older than the character as it was written, and suggested that Mildred instead be Angela's grandmother; McDonagh disagreed, feeling that it would change the story too much . McDormand's husband Joel Coen persuaded her to take the part regardless . McDormand took inspiration for her character from John Wayne; and Rockwell, wanting to make his character "the exact opposite" of Mildred, took inspiration for his character in part from Wayne's co-star in The Man Who Shot Liberty Valance, Lee Marvin . </P> <P> The titular location Ebbing, in the U.S. state of Missouri, is fictional . Principal photography began on May 2, 2016, in Sylva, North Carolina, and ran for 33 days . </P> <P> The musical score was written by Carter Burwell, who had also supplied the score for McDonagh's films In Bruges and Seven Psychopaths . As well as Burwell's score, the film features songs by Joan Baez, Monsters of Folk, Townes Van Zandt, and the Four Tops . </P>
