 In the gym scenes, since the extras were real High School Students,  the director faced the problem of not having enough of them because  of the SAT season, and many of them having already found out the  sometimes tedious process of working as an extra. As a solution for  the shots requiring a full gym to be seen, the director asked the  extras to move two or three times from their seats to look as if  there were more people with the help of editing. The wide shot  showing both sides of the gym was done in less than 20 minutes when  the teachers of Papillion La Vista Highschool asked more students to  join the film shooting.
