Executive Meddling: The producers wanted Jimmy and Dottie to hook up in the end. They also pushed for Dottie to save Jimmy from his drinking. The director responded with a single scene on the bus where Jimmy ends the conversation saying it was "time for a drink." Dottie takes his flask and hands him a soda.
Font Anachronism: The movie is set in 1943. The "Catch A Foul-Get A Kiss" banner is printed in the font "Banco", which was created in 1951.
Hey It's That Girl: Téa Leoni in a bit part as the first baseman (basewoman?) of the Racine Belles. She's the girl who scores the tying run on Kit's hit in game 7.
Throw It In: During his scene on the farm, Lovitz kept getting interrupted by the cows' mooing, prompting him to ad-lib, "Will you shut up?!"
What Could Have Been: In the original cut, there was a subplot where Marla Hooch got married right after the Western Union scene. She tells the girls she's pregnant, but asks them not to tell the coaches who would kick her off her team, and the girls make a promise not to slide into second when she's playing. Then in a game, Dottie's so distracted she doesn't realize Marla's playing second, and slides hard enough into her stomach to cause her to go to the hospital. The scene where Dottie is weeping was originally supposed to be her guilt over what happened with Marla, rather than a direct segue from Betty's tragedy.
And she's distracted because of another dropped subplot—growing romantic tension with Jimmy. They've shared a kiss and have been arguing about it, which is why Dottie is oblivious to the warnings about Marla. Her tears are guilt over injuring Marla and her slight infidelity.
