There is additional footage of Karl tormenting some chained female victims and also more of his death and some bloody lab shots in a version released on VHS in France in the 80s.
The UK cinema version was extensively cut by the BBFC upon release with edits to the opening staking, shots of dismembered body parts in the laboratory and a reduction to a scene where a tube is inserted into a man's neck to drain blood. Additionally the infamous dungeon scene, showing potential female victims chained to a wall, was completely removed. The 2005 UK DD Entertainment DVD features the same cut cinema print. The U.S Dark Sky DVD may be culled from a different print as the tube scene is completely intact, despite missing the other aforementioned BBFC cuts.
