Audio problem: In the scene where the Grabboid is pulling the truck with the chain attached and the guy is trying to shoot it, the gun noises do not match up with the muzzle flashes at all. At one point it is obvious he fires 2 shots, and yet 4 "bangs" can be heard.
Audio problem: After Agent Dammers shoots Frank in the arm, in the close-up he shouts, "I don't want to shoot you in the back...I said turn around!" In the next close-up of Frank, Dammers repeats the latter, though nothing is heard. (01:36:20)
Audio problem: Isabelle, in the bathroom, turns the bath on, then proceeds to have a heart attack. Slowly people come in and help her take her pills. No-one goes near the bath, and yet the sound of the running water is no longer there.
Audio problem: When the Geckos shoot Chet Pussy, the sounds of gunfire don't match the visible gunshots. (01:00:25)
Audio problem: Nancy shouts, "Yay Chris! Go long! Go for the pass, baby!" at football practice, and her voice is so distorted that the viewer can easily tell the line was added post-production (with too much gain).
