* DoingItForTheArt: Ford had desperately wanted to make this film for years, but had trouble finding a studio to back it. He finally made a deal with Republic Pictures -- which specialized in Westerns -- to film a Western for them in exchange for their VERY reluctant backing on ''The Quiet Man''. The Western Ford made was ''Rio Grande''; ''The Quiet Man'' went on to become Republic's biggest-ever box office hit, and the studio's ONLY movie ever to earn a Best Picture UsefulNotes/AcademyAward nomination. And Ford won his fourth Best Director award for this.
* FakeIrish: John Wayne and Ward Bond were Americans and Victor [=McLaglen=] was English.
* HeyItsThatGuy: All over the place. John Ford [[ProductionPosse worked with a regular set of actors]] in nearly every movie he made. Barry Fitzgerald, Ward Bond, and Victor [=McLaglen=] are the more notable names.
* RealLifeRelative: Town elder Dan Tobin -- the grizzled, bearded fellow who jumps up from his deathbed once he hears the epic donnybrook -- was played by John Ford's brother Francis Ford. The story has it they had not spoken to each other in years, but John asked Francis to star in this film and they were very amicable toward each other during production. Francis died a year later.
** Maureen O'Hara's younger brothers Charles and James Fitzsimons play Hugh Forbes and Father Paul, respectively.
** Barry Fitzgerald's brother, Arthur Shields, plays the Rev. Mr. Playfair.
* ThrowItIn: At the end of the film, Mary Kate whispers something into John Wayne's ear. It was an unscripted bit of dialogue that John Ford insisted O'Hara say to Wayne in order to [[EnforcedMethodActing get an unexpected reaction]] on Wayne's part. The three were the only ones who know what was whispered -- and now only [[SecretKeeper O’Hara]] is left.
