Revealing mistake: In the scene at the church, immediately after the girls were at the Suds Bucket, Mae is in the confessional when the priest drops his Bible. Mae steps out and kneels to pray as the priest opens the door to see who has just made their confessions. A closeup of the priest's face reveals that he has a "cowlick" (several locks of hair) hanging down in the middle of his forehead, but in the very next shot showing him in the background looking down at Mae, the lock of hair is suddenly gone.
Continuity mistake: During the music clip, when Jimmy is finally starting to take over the managerial duties of the team, there is a scene where he is instructing Beverly before batting. We see the very same spectators sitting behind the Rockford bench, who were there in the other scene where Jimmy and Dottie were concurrently instructing Marla before batting - which happened several games before.
Other mistake: The older Dottie Hinson in the beginning of the movie has blue eyes and Geena Davis (young Dottie) has brown eyes.
Continuity mistake: When Jimmy meets Dottie and Bob after the final game, we first see all three of them, with Jimmy and Bob shaking hands. While they are still shaking hands, the camera switches to Jimmy's head and upper body, and he is visibly not doing a handshake - instead within a second he is shown giving his hand again to Bob for a second handshake. Then, while he is still shown doing the second handshake, the camera switches to Dottie's and Bob's heads and upper bodies, with Bob visibly not doing a handshake. Finally the camera switches back to showing all three persons, with Jimmy just pulling back his hand from a handshake.
Continuity mistake: When the scout is watching Marla's batting practice in the gymnasium, the same shot is used twice when she hits the ball through the window. One far way, then one closeup.
Continuity mistake: When the selected team members are announced, we see Mae and Doris hugging each other in rejoice. About one second later Kit is shown rushing through the crowd, and we now see Mae and Doris standing about two meters apart from each other, both facing towards the notice board, with a couple of other girls standing between them.
Continuity mistake: During the championship game Kit is pitching for Racine and her sister Dottie hits a line drive that almost "takes her head off". Later when Kit goes to the dugout, a closeup shot shows her sitting with a jacket on her right arm crying and freaking out because Dottie got the best of her once again. But in the next shot, Dottie comes walking out behind the plate to catch, looks over at Kit who is still crying in the dugout, and the jacket is no longer on Kit's arm as it was just a second before.
Factual error: In the first clubhouse scene, Jimmy Dugan is given a baseball card to autograph, It is a standard size card, which didn't get made until the 1950s. A Goudey card, which would have been appropriate for Dugan in the late 30s or early 40s, was much smaller.
Continuity mistake: When Dottie and Jimmy argue about whether Marla should bunt or swing, Doris is cleaning a chocolate bar from her cleats. The first shot shows the entire heel covered, and she is cleaning it off. The next shot shows the heel is clean. Then the next shot is back to the entire heel being covered with Doris trying to clean the chocolate off.
Factual error: In the train scene, a Frisco (SL-SF) steam locomotive is shown, but the Frisco system did not serve Oregon.
Other mistake: When Helen Haley is helping Shirley Baker find her name on the team rosters, she finds her on the first list on the board. That list is the roster for the Racine Belies, not the Rockford Peaches.
Factual error: One of the stadium banners reads "Catch A Foul - Get A Kiss"; it is printed in the font Banco, which was created in 1951, eight years after the film is set.
Continuity mistake: When Marla is taking batting practice in the gym, she hits a ball through a window. In no other shot is the window broken. Also, when the ball is going through the window from the outside shot, the ball is going through a different window.
Factual error: In the final inning of the last world series game, Dottie is seen catching a pop up as she falls into the dugout. You see the ball go into her glove and then, before she even hits the ground in the dugout, the ball has moved to her throwing hand. There is no way a catcher would even attempt to transfer the ball from their glove hand to their throwing hand while falling like that.
Continuity mistake: When Jimmy is shouting at the team members to get on the bus, we first see Evelyn and Doris in the background while they are descending the stairs of the hotel entrance and hurrying on the pathway towards the vehicle. Then the camera angle changes, and we now see them from a close distance descending the stairs again.
Continuity mistake: In the end credits where they are showing photographs of the girls, Rosie O'Donnell is wearing a Racine Belles uniform. Kit was the one who got traded to Racine, not Rosie.
Character mistake: In the opening game Ellen Sue is pitching but the announcer states Kit is pitching.
Suggested correction: Kit is on the mound. Ellen Sue is playing short stop. But she's the one who beans the guy making fun of the girls, she just wasn't pitching.
Other mistake: The first time Kit is up to bat in the opening, she gets two strikes but holds on the third. Which is technically a ball that should have saved her. Yet gets called on a third strike.
Suggested correction: The 3rd pitch wasn't technically a ball. It was called a strike by the ump, so it was technically a strike. Not to mention it was down the middle and not even a missed call.
Guess the rules differed then for baseball, because technically Kit did a ball NOT a strike. Which I realise the ump or ref could have called either way. But fairly should have been a legal ball. And just because an ump or ref calls something, doesn't make it bank nor fair. They've made calls in games before, that were not what they claim. And her bat barely moved an inch. So, yes, it should have been a ball.
Balls and strikes do not depend on if the batter swings at the ball, it depends on where the baseball crosses home plate. The pitch Kit did not swing at was in what is known as the "strike zone" meaning whether she swung or not, it was technically a strike.
I'm just curious what makes you think it was a ball?
Deliberate mistake: During the Hall of Fame sequence at the end, Dottie sees the display about Jimmie hitting 58 home runs and there is a long wide shot of it as she stands next to it. Then there is a close-up of the bottom of the text which says born 1906 - died 1987, which wasn't present during the wide shot a moment earlier. The filmmakers likely saved this for the close-up for dramatic effect, but by blocking the initial shot without that part obscured it makes the text magically appear out of nowhere.
Factual error: Bob's ribbons on his uniform include the American Defense Service Medal which was issued from 1939 to Dec 7, 1941. Unlikely he'd have over 2 years of service (including pre-war) and only be a PFC. He was also missing the American Campaign Medal.
