Opening credits prologue: LONDON 1840

Before the discovery of Anaesthesia

The UK cinema version was cut by the BBFC to reduce shots of Rosa being caressed by Joe and to remove a brief shot of Joe's face scarred with acid. These edits were restored in video releases though the 2006 DD Entertainment DVD features the cut cinema print. In the U.S however the film was cut differently. The 'ravishing' of Rosa was left intact but 3 cuts were made to the stabbings of Bolton and the night watchman, and the surgical cutting of a patient's leg. The U.S Criterion DVD features the U.S cinema print though the cut scenes are presented as extra features on the disc.
