Continuity mistake: Mort spills his soda with the pile of papers on the table. As Mrs Garvey takes it off the table to hand back to Mort, you can see the bottom paper is wet from the soda. When Mrs. Garvey kneels down to clean the floor from the soda spill, The bottom part of the bunch of papers are still dry and untouched from the spilt soda. (00:10:35 - 00:11:10)
Revealing mistake: When Mort stops at the gas station to talk to Ted, and he gets out of his Jeep, the key is still in the ignition but there's no dinging from the door being opened (which we know it does from an earlier scene).
Continuity mistake: When Amy's house has been burned, one shot shows the rear quarter panel of a Saab 900 (Note long vent/plastic vent on quarter panel). Later when the car is fully pictured it is a Saab 9-3 (no vent panel in quarter panel).
Other mistake: When Amy goes to the cabin at the end (where she gets killed) she is looking for Mort. She calls out for the dog (Chico). Wasn't she told earlier that Shooter killed Chico? (01:22:00)
Continuity mistake: Amy arrives at the cabin and sets down her shoulder bag in the doorway as she searches for Mort. When she realises that Mort has become a homicidal maniac, she runs for her life, but she pauses long enough to retrieve her shoulder bag at the doorway as she flees the cabin. The camera immediately cuts to an exterior shot as Amy exits the cabin and runs for her car, but her shoulder bag has suddenly vanished and is never seen again.
Suggested correction: The bag falls off her right shoulder as she runs down the cabin steps.
