In the beginning of the film, the kids we see running through the woods at a distance, are not the actual kids that are cutting school. Due to lack of coverage, two other kids were brought in and dressed to resemble the regular kids. The doubles had to run through the woods to fill in some shots. All far shots were used to hide the fact that they weren't the same kids.
When Al was sneaking the safe out of the salon, two people passed by. The guy was the directors brother and the girl was a very good friend of the director. On the outtakes on the DVD, there is a take where the girl played a joke on the crew when she passed the store on cue with only a bra on.
While filming the last scene when Al, Vinny, and Angelo were in the car with the safe eluding the supposed cop car, the guys got into an accident. The driver of the car Angelo (Mike Lane), stopped at a yellow light and was hit in the back. The whole time this happened, the camera was rolling. The actual footage can be seen on the outtakes on the DVD.
