In the scene where Knudsen hits a home run, there are a few editing mistakes. The filming takes place in Shea Stadium. Well if the Generals were supposed to be the home team, they should have been wearing white uniforms. The other team, the Mets, where the ones wearing white. Also, the up close shot of the Mets pitcher, Dwight Gooden, clearly shows his number as 16. After the home run, the Mets pitcher is shown with number 76. Knudsen is a right handed batter, the distant shot of the home run, shows a left handed batter swinging.
