When the Babe gets out of the taxi at a night club, he sees the newspaper boys have a lot of newpapers left over. The Babe decides to buy them all. The stack is all messed up, but by the time he goes into the club and gives them to Phil, the newspapers are in a neat stack.
While the movie is rife with factual errors, some of the ones associated with the Yankees 1927 season are probably the worst. Home uniforms are depicted as white with pinstripes with the word "YANKEES" on the front. In fact, the home uniforms had nothing on them--only the away uniforms, in gray--carried the word "YANKEES" on the front. Mel Allen is depicted broadcasting the game where Ruth hits his 60th home run. In fact, the Yankees regular season games were not broadcast until 1939 and Mel Allen was only 14 in 1927.
The film depicts Yankee Manager Miller Huggins passing away right after the Yankees won the World Championship in 1927. In fact, Huggins actually died on September 25, 1929, nearly two years later. The Yankees finished in second place that year.
Claire was actually Babe Ruth's second wife. Helen, his first wife, was never mentioned.
The film claims that in his last game Ruth hit three home runs and a single. Actually in his final game the Babe went hitless in one at bat.
Babe Ruth's mentor, Brother Mathias, is shown visiting him while Babe is on his deathbed in the present day of 1948. Brother Mathias had already passed away in 1944.
When Babe leaves the field for the last time, Phil says "that ran your home-run total to 729". Ruth hit 714 home runs in his career. However, he also hit 15 in the World Series to give him 729 lifetime home runs in both the regular season and post-season.
Babe Ruth hit the home run for the sick boy, Johnny Sylvester, in 1926--not in the 1932 World Series when he called his shot (off Chicago Cubs' pitcher, Charlie Root). They were two separate events, in different World Series, and against different teams.
When Babe goes to join the Braves in Boston, his train is being pulled by a Southern Pacific GS-4 locomotive manufactured by Lima Locomotive. This model did not enter service until 1941, several years after the scene takes place. Further, the Southern Pacific never operated within a thousand miles of New York or Boston.
The song "Singing in the Rain" was published in 1929 yet the movie has Claire sing the song before Ruth and his Boston teammates at a theatrical show 11 years before it was published.
Ruth played for the Red Sox, not the Braves.
A disabled kid is somehow able to stand up after Babe passes him by and tells him, "Hiya, kid!"
Johnny is bedridden when Babe meets him. As he listens to the game on the radio, he miraculously gets better.
