Other mistake: When the three roommates take a taxi, Christine and Steve quibble over the fare, eventually handing their portion to Sir William. However, he never does pay the cabbie, rather he goes off to confer with his driver, Jimmie.
Other mistake: About 1 1/2 hours into the movie, Ensign Bordelles, in the courtyard of the American facility in Changsha, prepares his shore party to march back to San Pablo with the Chinese military escort on either side. The Ensign lines up his men and orders, "Detail, forward March." The Chinese soldiers, unlikely to understand a word of English, also move off in lock step with the Americans.
