Errors made by characters (possibly deliberate errors by the filmmakers): Although Bill Smitrovich's character is clearly an Air Force general, he is identified in the credits as "Admiral Higgins".
Factual errors: When the team arrives in Brazil, the game against England is constantly referred to as the team's opening game. However, in the 1950 World Cup the United States' first game was against Spain on June 25th. The game against England was played on June 29th and was the second game for the Americans.
Continuity: When Frank and Walter go to Joe's place of work, Frank lifts his arm to rest on top of a refrigerator then, in the next shot, he goes to lift it again.
