This is a comparison of the UK R-Rated version (PAL) and the Unrated version (NTSC) which comes with Spanish subtitles.
103 Sec. Cut = 1.43 Min.
The beginning has been recut. The R-Rated shows text followed by a shot of the house. In the Unrated the shot of the house is placed before the text.
The blood-smeared woman can be seen two times in the Unrated.
Film tear in the Unrated.
Here the UK version (R) I have at hand has a defect. The screen turns black and a whistling noise is audible before the next scene starts.
After the guy stabs the woman whose legs have been amputated in the stomach with a wrench the whole "Guinea Pig" style disembowel sequence is missing. Several shots of the woman and the man are presented before all the intestines of the woman are ripped out in a close-up. In the end we see the disembowled woman from a bird's eye view.
