During the dream sequence, while Jax speaks to 3 different individual, the phone rings 5 times.
During post-production, this film and The Waiting Game (2014) suffered a major scare when Timothy David Mitchell's hard drive containing the footage of both films became damaged, resulting in the loss of all footage. Mitchell gave his hard drive to a friend who had been recovering data from other damage hard drives for people at the student hostel were Mitchell was living at during this time. A large quantity of the footage was retrieved, with only a few files permanently lost. Sequences that required lost footage were replaced with pre-exported draft versions.
