Compared is the cut UK tape by Warner (rated:X) and the uncut German DVD by CMV Laservision.
2 seconds in 1 scene are missing.
In Great Britain the movie was released on tape in the early 1980s and was rated X, what said the movie was not suitable for youth below 18. Until 1982 the X certificate existed until it was replaced by the 18 certificate of the BBFC.
Of course, n uncut version by ILC Prime/MGM was released.
One can see the rotating chainsaw longer in Vincent's body. Blood and guts are flying around.
