Iris is in intimate scenes with all three of the popular guys at one point in the film. She is with Big John at the first party he has at his house, then she is with Ricky at the school dance, and then she is with Ronald at the New Year's Eve party at Big John's house.
The scene where Cindy and Ronald jump the perimeter wall and explore the Regeneration Group Aircraft Bone Yard was shot at Bob's Air Park, an aircraft recycler just outside the Boneyard, which has since been sold.

When the guys go to egg Kenneth's house on Halloween night, all three of them try to disguise themselves by wearing all black clothing and putting black paint on their faces.
