Continuity mistake: During the chase scene with Robotnik's robotic vehicle, at one point an EMP device is launched which misses Tom and Sonic's pickup truck and instead latches onto a minivan in front of it. Except just a few shots prior, there was a wideshot of the road, and you can see that Tom's pickup truck and the robotic vehicle were the only cars on the road. The minivan just sort-of... appears.

Continuity mistake: At the beginning of the movie, we see a portion of the climax where Robotnik is chasing Sonic. At one point in the very first shot, he runs up the side of a building, onto the roof, then back down. However, when we see the complete chase at the end of the film, he never runs up that building.
