Continuity mistake: After running the roadblock and getting shot in the shoulder, we see Hopper's shirt with a bloody patch about 3" x 2." The camera angle changes and it is now several times larger, positioned differently and oddly-shaped (a bleeding wound would simply expand the stain on the shirt; it would not 'move'). (00:02:55)
Continuity mistake: When the bad guys create a roadblock with their 2 cars as Hopper drives his girlfriend to her mother's house, the cars stop with one on one side of the yellow line, and the other stops with the steering wheel over the line. The camera angle changes, and now both cars are neatly, evenly positioned, with their engines sitting over the line. (00:02:05)
