Continuity mistake: The reporters in the movie are hiding and video tapping the "drug deal gone bad" at the beginning of the movie. For the location that they are taping, there isn't any movement, they stay in one place. However, when the kids are watching the tape both times, it seems to be like an actual tape of what was going on, not what they could have taped, because, not only do they have cuts (going from one actors face to the next with no transitions) but they also show a shot where you could see where the cameraman was hiding, little hard for him to hit that angle!
Continuity mistake: When Jackie is on the horse drawn carriage, and it's crashing into the shop signs, one of the bad guys is thrown and lands on one of the signs - Academic & General Book Stores. However, after this shot, the horse carriage keeps going forward past the shop. In the next shot, another bad guy crashes into a shop window - but what shop is it? The same Academic & General Book Store.
Continuity mistake: As Jackie walks through the park with the tape to trade for his girlfriend, at least one woman, perhaps two other people, are walking in the same direction as him. Seconds later, when his girlfriend cries out, we see Jackie, with those same people now walking towards him.
Continuity mistake: In the beginning, when Jackie is doing the cooking show, the guy doing the talking says what Jackie is doing such as, "kneading the dough". Later, when Diane is watching the same tape, when the voice says "kneading the dough" the picture show Jackie twisting the dough, which happened a minute or so later than the kneading.
Other mistake: In the scene near the end when Jackie drives the big truck through the house, there are explosions everywhere, in solid concrete, and huge sparks from tiny wires. And when did thin wood pieces like the wooden tower/pavilion outside start to explode? Nothing modern or metallic was placed on this pavilion, so that can't explain the explosions.
