The IMDb has this to say about The Curse of the Werewolf: “The film had considerable problems with the BBFC on its initial cinema release and was subsequently cut by around 5 minutes before release. Much of the edits were made to the beginning of the film and involved the complete removal of the scenes where the servant girl is attacked in the castle dungeon, and her later confrontation with the Marquis (which results in his fatal stabbing). Other cuts included heavy edits to the murder scenes and a shortening of the bedroom scene between Leon and the prostitute. The 1995 Warner VHS featured a print often shown by BBC which featured different cuts. Much of the above was intact (bar for a reduced stabbing) though additional shots were missing including scenes showing dead bodies, shots of dead goats, and much of the climactic killing of the werewolf, including his deafening by the bells, the bloody gunshot wound, and some shots of his dead face over the closing credits. The film was later completely restored with all the missing footage intact and first shown on BBC in 1994, and this version was released (on Region 1 DVD only) as part of Universal's "Hammer Horror Series" 8 film box set. The 2010 12-rated DVD features the same restored and fully uncut print.”
This Blu-ray release of The Curse of the Werewolf from Shock is rated a mild “M” and I must say it is unlikely to cause any censor troubles. While I have no comparison, I will say that the attack on the servant girl is very truncated, as is the scene where Leon kills to prostitute, while the stabbing is not particularly bloody. I cannot say for sure, but I think we still in this release have a censored version.
