Near the end of the film when the kids are skating Tron arrives in his truck. When the truck is seen pulling up only the rear wheels are moving. The front wheels are not moving yet the truck is driving forward.
When they are first driving to Fort MacMurray you can see the camera man in the back seat of the car. When the semi trailer passes by them with the pipes on the back.
When Dean & Tron are fighting toward the end of the movie, just after Tron falls into the Christmas tree and the camera moves back to Dean, you can see the wire from the microphone attached to his clothing on his stomach.
When Terry, Trixie & Dean are driving from Fort McMurray to visit West Edmonton Mall, they are shown driving under a highway sign referring to Edmonton as being to the north, with an exit to Rimbey. Edmonton is south of Fort McMurray, & Rimbey is south of Edmonton, so the shot was evidently taken when the filmmakers were traveling from their Calgary base to Edmonton.
