Corrected entry: Near the end of the movie in the scene where Ludwig is man-handling Jane (Presley) up the stairs of the ballpark, she is screaming but if you look closely in several shots during the struggle it is clear that is a stuffed dummy of some kind.
Corrected entry: Towards the end of the movie when the baseball scene is showing highlights as the song "I Love L.A" plays, you'll notice in one scene when a grand slam happens that 4 players cross second base. This is impossible since only the batter and the man on first should cross second base.
Corrected entry: In the scene where Frank sets fire to Ludwig's office, just after the sprinklers start, you see a closed blind or shutter covering a window behind a lamp behind Frank. The shot then briefly cuts away. When it cuts back to Frank, the blind is half-open and in the process of automatically closing. (00:44:40)
Corrected entry: Victor Ludwigs beeper device was designed simply to temporarily hypnotize the wearer and make them carry out whatever command he had inserted. It was not designed to turn them into full on villains. So the reaction of the Doctor at the Hospital (after being distracted, fighting off frank and fleeing halfway across town in a fully conscious state) is totally ludicrous.
Corrected entry: At the onset of the baseball game, the first Mariners batter is announced as "Mariner's lead-off hitter and shortstop, Jay Johnstone." A few minutes later, right before Frank Drebin starts purposely calling every pitch a ball, the Mariner batter at the plate is announced as "Shortstop, Armando Pershoni"
Corrected entry: An air bag is shown to have deployed in Drebin's car after hitting some garbage cans. Air bags didn't become available in the Ford Crown Victoria until 1990 but the movie came out in 1988. Such a minor impact wouldn't have deployed the air bags anyway even if the car did actually have them.
Corrected entry: When Frank is trying not to get the third out to the seventh inning stretch, and he throws up a bunch of balls to confuse the catcher, when you see a shot of the balls in the air, you see five balls, but he only throws up four, and you only see four drop.
Corrected entry: In the film, the Angels' game is played in Dodger Stadium, which is not where the Angels play their home games at the time of the film.
Corrected entry: The Angels score a grand slam home run, but it is not reflected on the scoreboard. There should be at least a "4" shown in one of the innings, but there isn't.
