When Eileen and Major Gruver visit Nakamura backstage, Gruver says he thought the kabuki performance could have used Marilyn Monroe, and Nakamura allows that he too is a fan of Miss Monroe. In 1957, when the movie was filmed, this conversation would have made sense. But it takes place in 1951, at a time when Marilyn Monroe was still a small-part player, little known to the public. It is highly unlikely that even Gruver would have known who she was, and impossible that Nakamura would have, that early in her career.
Several times during the movie salutes are improperly exchanged between officers and between officers and enlisted. Military protocol requires the salute of the junior officer to be held until returned by the senior officer. The same thing applies when an enlisted man salutes an officer of any rank.
After the doctor examines him, Maj. Gruver buttons the left coat sleeves and after the right sleeve, keeping his left hand handling the right sleeve. In the next shot he is handling the left sleeve with his right hand.
When General Webster tells Major Gruver that he's being shipped back to the States, he says that he's being sent to "Randolph Field." This is an mistake because Randolph Field was renamed Randolph Air Force Base on January 13, 1948 and this movie takes place during the Korean War (1950-1953), more than two years later.
