Continuity mistake: In the last game of the movie you can see that Ray Mitchell (Angel Player) hits a home run to tie the game. If you look you can see that the home run ball goes over the fence and out of the stadium but then after they change cameras to Ray and then back to where he hit the home run it shows a man with the ball in his hand as if he caught it.
Continuity mistake: When Knox meets Roger at his house, he asks if JP can speak, and later is surprised when he tells him "Thank you for the ride home". However, five seconds earlier, Roger had looked at his photograph with Knox in full earshot, and JP had said "It looks like a prison photo".
Continuity mistake: In the scene in which Maggie is making her speech about faith and angels, she makes a joke about there being angels playing baseball. In the wide shot, Adrien Brody cracks up big time, with his whole face splitting into a wide grin. But when it cuts to a close-up, he is suddenly somber and solemn.
Continuity mistake: The first three games shown in the movie take place on three consecutive days, yet on each day they are playing a different team on each day. This is impossible considering that back then they only played 3 or 4 game series with each team. The only way that that is possible is for the first game to be the end of a series, the third game is the beginning of a series, and the middle one is a make up game, the only way a make up game would be scheduled like that is if they ran out a regular games that could be converted into double headers, but as early in the season that it is, that is very unlikely.
Continuity mistake: In the scene where the ball is "magically" flying all over the place there is a shot of the scoreboard with the errors being added on (it ends with about 15 and counting) but two shots later it starts at about 15 again.
Continuity mistake: In the scene where Al is sleeping in the lounge chair in center field, a player runs after the ball, jumps over Al and continues after the ball. If Al is invisible, why did the ball player need to jump over him?
Continuity mistake: In the last game the commentator announces "not an empty seat in the house" yet when the pitcher catches the ball in the last pitch, there are quite clearly hundreds of "empty seats" behind the extras-crowd.
Continuity mistake: In the final game, when pitcher Mel Clark is about to throw his first pitch to the White Sox batter named March, a shot showing March from the pitcher's view shows March taking his step that a batter normally takes about when the pitcher is releasing the ball. However, in the subsequent shot, Clark hasn't even started his windup.
Continuity mistake: At the end of the movie when Tony Danza is pitching to the last batter, the batter hits a ball that is very low to the ground, and it appears as if it is going toward either shortstop or center field. But the announcer and camera shots indicate that it is headed toward the left field foul pole, and eventually going foul. How could it change directions like that?
Continuity mistake: Throughout the movie, Roger and Coach Knox chat it up while a game is going on. According to MLB rules, it would be a violation for players/coaches to be chatting with fans like that.
Continuity mistake: Throughout the movie, the angels used two different stadiums. They used the Big A (as that is what it was called in 1994), then they also used the Oakland Coliseum as well.
