Continuity mistake: In the beginning of the film John and Detective O'Hara are driving. She suddenly gets really sick, so John stops the car so she can get out. She runs and then throws up. When she comes back to the car she trips on a log that was never there before. (00:19:45)
Continuity mistake: On Kimble's first day as the kindergarten teacher, he's wearing a white shirt with jeans and a jacket. When he shows up the next day and is talking with the mother of one kid, he's wearing a maroon shirt with khakis. They then cut to the kids doing the pledge of allegiance, then to the kid eating everybody's lunches. In that shot Arnold is wearing the white shirt, jeans, and jacket. But then, they cut to "Who is your daddy, and what does he do?" sequence, and Arnold is back in the maroon shirt and khakis. It seems the "Lunch-box kid" part was in the wrong spot.
Continuity mistake: Toward the end of the film while the school is on fire, Kimble's partner runs to the side door gun drawn. She is spotted by Crisp's mom and is hit by her car, knocking her down. When she arrives shortly with a bat to save Kimble she is much more banged up than when she was first struck, most noticeably a rip on her right shoulder that wasn't there before.
Continuity mistake: In the scene where Phoebe is interrogating Cindy, Cindy refuses to testify or identify Crisp in the line up. She then tries to leave the interrogation room, but it's locked. When the interrogation is over, we see that Phoebe opens the same door without any problems, or anyone opening it from the outside. (00:08:38)
Continuity mistake: After the kindergarten class have finished their speech, the little kid who spoke last turns around and begins to jump up and down. When the shot changes as the principal starts to speak, he is facing the front, standing perfectly still.
Continuity mistake: Toward the end of the film while the school is on fire, Kimble's partner runs to the side door, gun drawn. Phoebe is spotted by Crisp's mom and is hit by her car, knocking her down. Crisps mom's hair is pulled back, but when she is in the school locker room and discovers Crisp shot dead her hair style is different, not pulled back.
Continuity mistake: Earlier in the movie... when Kimble is looking for Cindy (just before the "line-up") and Arnold says the line - "Alright party's over, everyone go home" he tosses some guy onto the glass coffee table which gets completely destroyed. Arnold's next line a moment later is, "next time, my place." The next scene, the coffee table appears good as new and the the guy is no longer there.
