The original UK cinema and initial 1989 CIC video releases were cut by 19 secs by the BBFC to remove shots of underwear removal and closeups of neck strangling from the murder scene. The cuts were restored in all later Universal video & DVD releases.
ABC edited 9 minutes from this film for its 1975 network television premiere.
The main titles were completely redone for the 2012 Blu-Ray release. This includes a completely different font, and quite a few typos were accidentally left in.
