See Spot Run (2001) - 13 mistakes

Factual error: When Stephanie gets in the back of the zoo wagon, she discovers a zebra back there. Then all of a sudden the zebra toots and the flames go way out of the back of the trailer. In real life that wouldn't happen because the gas doesn't come out of your rear end fast enough to have that happen.

Other: When Stephanie (the kid's mom) gets sprayed with mud by the bus, it is accelerating as much as it can in reverse. Why would it accelerate so much in reverse if it's trying to avoid falling down the hill?

Other: At the FBI facility, Agent 11's handler buckles the collar on the dog's neck. Later, when Gordon has put the collar on and tries to get it off, he's trying to pry it off. He just buckled it on not two minutes earlier. He's stupid, but not that stupid.

Revealing: In the beginning, Gordon is driving his truck and "drinking" something out of a thermal mug. He's be-bopping around so much it would have spilled all over him. If you look closely, you can see he's not really drinking at all.

Continuity: In one scene in the mail guy's apartment, you can see the clock behind his friend, but a couple of shots later (only a moment) the time has changed quite a bit.

Continuity: In the pet shop, Gordon gets all wrapped up with plastic wrap. Just a few short scenes later it's gone. There's no way he could have gotten himself out of it in that amount of time. Also, the "plastic" fishbowl shatters - plastic fishbowls like that are not that rigid and would not break like that. Add to that the "piranha" tank is obviously a bubble line at the back of the tank - you can see the bubbles come up when they reach the fishnet in.

Other: When Steph is waiting for the babysitter, and Gordon walks into her apartment, we hear her saying on the phone "Yeah, flight's at nine". But when Gordon takes the kid back to his apartment, and they are watching the time tick by, the clocks reads somewhere around seven o'clock.

Continuity: Towards the end, the mail truck has a reflector hanging outward on the driver side. Later scenes, it's back in place.

Revealing: At the beginning of the film when Gordon is delivering the mail to Spike's house, Spike gets loose and chases Gordon. Gordon runs to a tree, and somehow he flies all the way up to its branches.

Continuity: During the end of the movie, spot is in the park again, and when he looks at the bad guys, he has a collar on and then when he looks back, it is off. This happens for a minute or two.

Continuity: When the boy gets a call from his mom, she is far away from the truck. When it spits mud up, she is right next to it.

Continuity: In the opening sequence, the driver's door on the mail truck is wide open. When the protagonist arrives at his destination a moment later, the door is closed.

Continuity: In the first scene the little boys mom is covered in mud then it switches to Gordon then it goes to her again and she is hardly covered in mud.
