Factual error: When Hawkeye and Trapper arrive in Japan, as they approach the hospital in a Jeep, you can see a football field in the background. Look closely at the goalpost on the field. Instead of looking like an "H" (then in use), it is in the style used since the late 1960s: a bent single goalpost, a crossbar, and the uprights.
Factual error: In the football game scene, the players all have helmets with modern style (1970's) face guards.In 1951, the time period of the film, no face guards were used.
Factual error: The goal posts in the fifties were at the goal line, in the movie they are in back of the end zone.
Suggested correction: The goalposts were at the back of the end zone for college football since the 20's. It was only the NFL that had the goal posts on the goal line, so the scene is accurate since it wasn't an NFL game. It should be noted too that the NFL didn't move the goalpost to the back of the end zone until 1974, 4 years after the movie came out.
Factual error: Early in the movie, the loudspeaker announcer states that the Korean War was the #1 news item of 1951. Later in the movie it is announced that the night's movie is scheduled to be "The Glory Brigade" starring Victor Mature. However, that movie was released in May of 1953.
