The UK release was cut, the distributor chose to remove one shot, showing a hero sadistically twisting a knife into a guard's neck, in order to obtain a 15 classification. An uncut 18 classification was available.
The director's cut contains 10 minutes of additional footage plus alternate takes, dialog and soundtrack. (It was first officially released in the summer 2011 on Epix HD and US cable pay per view, before being released on Blu-ray in December 2011.)
