Deliberate mistake: After having wrestled with Santini in his office, Col. Virgil Hedgepath tells Santini, "And no more assaulting corporals in the latrine." Marines use the naval term "head" in refering to the restroom, and would never call it "the latrine." However, since "latrine" is better known to civilians, this could be a deliberate mistake by the film makers.
The Great Santini (1979)
1 deliberate mistake - chronological order
Directed by: Lewis John Carlino
Starring: Robert Duvall, Blythe Danner, Michael O'Keefe, Lisa Jane Persky
Genres: Drama
Factual error: When Santini is reporting into Beaufort, he refers to the Marine behind the desk as "sergeant." However, the rank on the Marine's sleeve indicates he is a Master Gunnery Sergeant. Unlike in the Army, referring to any rank other than E-5 as "sergeant" is considered an insult in the Marine Corps, and no Marine would ever refer to a Master Gunnery Sergeant as "sergeant." The proper form of address would be "Master Guns," "Master Gunny" or "Top."
Bull Meechum: I'd like to propose a toast, to my son. He is eighteen today. He has just ordered his first drink. Before he drinks it, I'd like to wish him a long life, a wife as fine as his mother, and a son as fine as he's been. To my son.
Trivia: Although Blythe Danner plays Michael O'Keefe and Lisa Jane Persky's mother in the film, she is only 12 years older than them.
