Revealing mistake: When the builders are committing suicide the guy in charge keeps turning earlier to the areas of the falling instead of after they land. A special FX and timing error I guess. (00:06:20)
Continuity mistake: When the woman shows the video at the Filbert restaurant of the man being mutilated by the lions, the position of her hand holding the iPod changes between the front and back shots. (00:24:25)
Deliberate mistake: When the red jeep is driven into the tree, two of the occupants are thrown through the windscreen with such force that they land about 15 feet away from the vehicle, one of whom was sitting in the back. But John, who was in the front passenger seat with no seat belt on stays put. Then calmly gets out seemingly uninjured? (00:32:30)
Continuity mistake: After the private starts shooting and the group Mark Wahlberg is in breaks into smaller groups and starts running in the field ahead of the wind, his group consisted of himself, his wife, the little girl, Jess, and two women. One woman was heavyset wearing blue with dark hair. The other was thin with red hair. The next scene of them running ahead of the wind, their group now has two boys, one black, Jerry (I think), one white, Josh (I think), instead of the two women. (00:48:28)
Factual error: Filbert is in the southwest corner of PA. It is very far out of the way of Harrisburg and completely off the route from Philadelphia to Harrisburg.
Factual error: There are no tracks, stations or train routes in Filbert, PA.
Continuity mistake: When the Jeep stops in Priceton, we can see its on a single land road. However once it starts to accelerate in the next shot to ram the tree at the intersection, it is now a forked road.
Suggested correction: The road is a standard two way road that is unpainted with road markings. Almost all non major roadways are unpainted and many of them fork into two separate roads.
Factual error: The cars the train is pulling for the Philadelphia to Harrisburg route are not ones that represent any passenger cars used for the Amtrak or Keystone routes. They are SEPTA cars on an undisclosed route, other than the Harrisburg line.
Revealing mistake: When they are sitting down for dinner at the old lady's home, it is clear that a very white light source is in the room brightening things up - something that non-electric oil/kerosene light sources cannot do.
Continuity mistake: In the very first scene where Elliot comes home and finds Anna sitting on the couch we see that the handbag she has is black but a couple of minutes later it's changed to yellow.
Continuity mistake: When the train first leaves Philly heading to Harrisburg, there are 4 cars pulling out and 5 on the overhead shot. Also when pulling out of Philly it is a diesel engine and the overhead is electric.
Other mistake: When the Jeep crashes and John gets out, he sits on the ground behind the vehicle and picks up a shard of glass that's supposed to be from the vehicle accident. Given that all the glass on the jeep shows to be intact, the glass couldn't have come from the Jeep as insinuated by the audio and placement of the shard.
Suggested correction: The windshield broke when the Jeep crashed into the tree and the driver was thrown through it. So the glass of the Jeep is not all intact. That being said, the shard John picked up was a long way away from where the windshield broke.
