Blood splashes were digitally removed from both impacts to bodies and blood on blades of weapons, achieved through the darkening of certain shots and by digitally erasing blood from the image. When the finished film was submitted to the BBFC for a formal classification, the BBFC stated that more cuts would be needed in order to secure the 12A. These included the use of alternate footage and the digital removal of blood. Four scenes were changes, removing bloody violence, threat and a scene of injury. The BBFC explained a 12A rating would be likely if the violence was toned down.
A rough cut of the film was submitted to the BBFC in the UK for an advisory screening, a process used by filmmakers to see how likely a film will obtain a certain rating.
