While filming at the MB2 Raceway, Nathan Reid's steering capability became disabled after a collision with another car, slamming him into a wall at around 30mph. Fortunately production was completed with filming and actor only suffered minor injuries.
Writer Nathan Reid's three main friends from high school were Nick, Chris, and Andrew, who are all lead characters in the film.
In a driving scene in the movie, Andrew says, "Don't even think about putting that jock strap on my mouth again. F*****, "Andrew needs oxygen bull****".
This is based on a real prank pulled on Andrew in real life where after falling asleep Nick placed a jock strap cup that he had worn for 2 days straight over Andrew's face while he was asleep, all caught on video.
All the pranks filmed in the marketing of this movie were conceived by writer Nathan Reid, who had subsequently pulled off these same pranks in high school. Production talked Nathan Reid out of "The Family Guy Prank" where a large man fights another man in a chicken suit at Hollywood and Highland, giving homage to this famous cartoon battle.
Actor Luis Jose Lopez was the only actor screen tested for the role of Chris. Writer Nathan Reid had no back up if he wasn't perfect for the part.
