This is a comparion between the UK DVD from Momentum with the uncut German DVD which is a part of the Emmanuelle Box.

As one could already read on the bbfc Homepage, Momentum had to cut out about 38 seconds of the movie to get a BBFC 18 rating for the DVD. By now, the movie was also released uncut. In 2007 Optimum Home Entertainment let the BBFC re-rate the movie which resulted in a BBFC 18 rating for the uncut edition of the movie.

There also exists a Bootleg-Boxset that includes the movie; this DVD is (considering the run time) identical to the Momentum DVD, so it is the same cut version.
Run time:

German DVD: 90:03 Min.
UK DVD: 89:28 Min.

[01:18:06]

The rape-scene in the opiumden was cut out. Emmanuelle gets pushed on the floor by one of the two men while the other one rapes her. After that the movie fades to Mario.
