A cut from Elwood in the back of the car that brings him to the academy to a clip of Sidney Poitier and Tony Curtis in a similar setting at the beginning of The Defiant Ones, for instance, suggests a bit of psychic recall: a character drawing from his own pop-cultural frame of reference as a way of coping with his own horrific circumstance.
And while “Nickel Boys” is mercifully far too experiential and self-possessed to end with a series of sobering title cards about the history it depicts, there's a palpable sense of implication in the recurring use of film clips (Stanley Kramer's “The Defiant Ones” is a major point of reference) and news footage, which serve as damning reminders of culture's selective myopia.
Ross repeatedly references scenes from Stanley Kramer's classic The Defiant Ones (1958), wherein prisoner Sidney Poitier is changed to the racist Tony Curtis as they flee authorities, eventually bonding over the experience.
Still, I am hard-pressed to think of a film that uses footage from another movie as thoughtfully or as powerfully as Nickel Boys uses moments from The Defiant Ones, Stanley Kramer's film about two prisoners (played by Tony Curtis and Sidney Poitier) who escape from their incarceration in shackles and must learn to work together, despite their differences.-Dissertations will surely be written about the camerawork in this movie, not just for its POV but for its choices of specific angles, particularly its repeated motif of images looking directly up at the sky, or, in the shot that has become the film's main poster, up to a mirrored ceiling reflecting the two protagonists back at themselves.
Ross additionally intercuts other forms of media, like videos that appear to be taken straight from YouTube as well as scenes from other films, like the 1958 Tony Curtis and Sidney Poitier movie "The Defiant Ones."
Even beyond the canon of films that valorize the Confederacy and the Old South, movies have white heroes with whom audiences can identify: Robert Shaw in Glory, Skeeter in The Help, Agents Ward and Anderson in Mississippi Burning—even Tony Curtis' Joker, who begrudgingly comes to respect fellow chain gang prisoner Noah Cullen (Sidney Poitier) in The Defiant Ones, a movie Elwood watched at Nickel.
