Ice Station Zebra (1968)
1 other mistake - chronological order
Directed by: John Sturges
Starring: Ernest Borgnine, Rock Hudson, Patrick McGoohan, Jim Brown
Plot hole: Patrick McGoohan shoots the marine captain thinking him to be the traitor, thus, McGoohan believes, stopping the marine killing Ernest Borgnine. But shortly afterwards McGoohan comes out of the hut and addresses Borgnine sarcastically as 'Comrade'. How did he know he was the real traitor? Nothing has yet happened that should cause him to see this truth.
Cmdr. Ferraday: We operate on a first-name basis. My first name is Captain.
Trivia: The famed aviator Howard Hughes was supposedly obsessed with this film, and sources claim it was his favorite. In his later years as a recluse, he allegedly would watch this film daily in his private theater.
