During filming, it was said that the trap used on Whannell was revealed to be fully functional and very rusted, making it very dangerous. The version of the trap used in the full film was made safer and had artificial rust. Wan later revealed that the film was shot in just over eight days. Upon completing the film, the pair traveled to Lions Gate studios to screen the film. Lions Gate immediately accepted the deal and got approved for a budget to make their script into a full feature film. Instead of being paid in advance, Wan and Whannell agreed to take a percentage of the profits from the film's release, which turned out to be much more than initially expected.
