Corrected entry: In the scene where Roger Maris, Bob Cerv and Mickey Mantle are watching 'The Andy Griffith Show', they show the beginning and play the theme song, but it's in colour and you don't hear the announcer's voice. At the time, 'The Andy Griffith Show' was filmed in black and white and there was an announcer until the mid-60s.
Corrected entry: Throughout the film, anytime the baseball is shown in close-up (as when being pitched, etc), it appears to be a modern-day Rawlings American League baseball (with "Rawlings" either covered over or not visible). In 1961, where the film was set, the manufacturer of official baseballs for the majors was Spalding.
Corrected entry: When Roger Maris is on his final shot to get the 61st homerun in the same amount of games as Babe Ruth, he misses by hitting the ball with a check swing. When he hits it, the ball is traveling to his left, towards third base. In the next shot, the first baseman picks it up and tags out Roger!
Corrected entry: In many of the games, Yogi Berra was announced as a left fielder, when he was in fact a catcher.
Corrected entry: In one scene, the Yankees are playing the Twins. The Twins didn't exist until the following year when they moved from Washington.
