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. The BBFC explained a 12A rating would be likely if the violence was toned down. Four scenes were changes, removing bloody violence, threat and a scene of injury. These included the use of alternate footage and the digital removal of blood. 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. 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. The BBFC then gave the film a 12A rating for cinema release. This pre-cut version was released on DVD in the UK with a 12 rating. However, the US PG-13 version was submitted to the BBFC for the UK Blu-ray release, which was classified '15' uncut.
British theatrical version was cut for violence (sights of blood) to secure a more commercial 12 rating. The DVD includes the cut version, Blu-ray the uncut version (with a 15 rating).
