The Great Santini (1979)

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."

Ben Meechum: Would you like to die in action, Dad?
Bull Meechum: It's better than dying of piles.

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.
