- Playing Gertrude: John Wayne was 41 playing a man pushing 60.
- Throw It In!: When Sgt. Quincannon is addressing the troops and warning them to "watch them words", he asks who owns a dog, without receiving an answer, and concludes, "Nice dog! Irish setter!" The scene was improvised on the spot by John Ford. The dog was an unnamed Navajo pet that had fallen asleep during the set up. Multiple takes were required because McLaglen kept blowing the line, calling the dog a "cocker spaniel".
