Continuity mistake: When Gord receives his car in the beginning of the movie the sky looks really dark, and the ground is wet as if it were raining, and in a couple of shots of Freddy it looks as if it is raining in the background, yet in the previous and following scenes it is bright and sunny.
Continuity mistake: When Betty is testing her rocket wheelchair she is parked in front of some white lines, when Gordy pulls up, the lines aren't there.
Continuity mistake: In the scene in the offices of RadioHead animations, Gord is holding a large envelope package. He is also given a note which gives the name of a restaurant that Dave Davidson is eating at. Watch the note and the envelope switch hands MANY times in the scenes.
Continuity mistake: Gord builds his halfpipe and it shows it completed, then later in the movie, it shows the outside of the house with the speed increased and it shows a partially complete halfpipe.
Continuity mistake: When Gord's father is outside hooking his truck's winch up to his skateboarding ramp he pulls out of the driveway but at the angle he starts driving it would be impossible for it to be hooked up properly.
