This film is apparently based/inspired by the life story of John Bishop (from Liverpool UK). Will Arnett and John Bishop apparently met and Arnett wanted to make his story a film.
The cast includes one Oscar winner: Laura Dern, and three Oscar nominees: Bradley Cooper, Andra Day, and Ciarán Hinds.
Emily Blunt was originally courted for the lead role but scheduling conflicts with The Dish (2026) prevented her from being in the movie.
