Loosely based on the house party of Corey Worthington (Delaney) in Australia. The then-teenager posted the address of his house party on MySpace, attracting around 500 people and caused over $20,000 in property damage. His party attracted journalists and was widely disliked by the public, having been assaulted by a group of teenagers after the events.
Some of the footage was shot by the cast with cell phones, Flip, iPhone and Blackberry phones that were handed out by the crew. Over 10 hours of footage was recorded mostly due to the cast continuously recording.
When the camera catches the young lady urinating, she gestures for it to shoo away. According to a popular Internet rumor, the lady was urinating in a corner due to a lack of bathrooms on the set, and was irritated by this violation of her privacy. Only by paying her an extra amount of money were the editors allowed to use the footage in the film. However, her expression is ambiguous, and she almost appears to be smiling or laughing while gesturing the camera away from her body function.
