From that innocent question comes this poignant piece of Hollywood (and American) history, courtesy Charles Laughton, who answers that question by reciting in full (and I suspect, for the only time in a movie) the Gettysburg Address.  (H/T to Msgr. Ogle for unearthing this gem!)

The scene below comes from the 1935 movie “Ruggles of Red Gap.” Happy 4th of July!
