True Grit/Trivia

Dawson Casting: Mattie. In the book, she's about fourteen -- and prepubescent. Kim Darby was well into her twenties.
Playing Against Type: John Wayne usually played straight heroes, not middle-aged drunken Anti Heroes.

Billing Displacement: Josh Brolin is billed third and above the title, but doesn't appear until an hour in and has somewhat less presence.
- And Starring: Hailee Steinfeld, despite being the protagonist, is the last name to appear in the credits. This may be partially due to this being her first film.
Dawson Casting: Notably averted this time, as Hailee Steinfeld was 13 at the time the movie was made.
Disabled Character, Disabled Actor: A woman missing her left forearm (due to a birth defect) was hired to play older Mattie in shots that don't show her face. She winds up having more screen time than the actress that plays older Mattie, mostly due to the long shot at the end of Mattie walking away from Rooster's grave that lasts into the credits.
Hey, It's That Guy!: After haggling over some horses with Doug's dad, Mattie witnesses the ignominious hanging of John Redcorn.
- Lucky Ned was the sniper Daniel Jackson!
Hey, It's That Voice!: The voiceover of the lawyer as Mattie reads the letter is an uncredited J.K Simmons AKA Cave Johnson, J. Jonah Jameson, etc...
