The (censored) Director's Cut has been compared to the (uncensored) Extended Cut. Both versions are contained in the UK-DVD by Prism Leisure and only differ from each other through alternatively shot topless-action in the Extended Cut. There is not any more violence, like some websites claim!
Runtime of both versions: 82:50 Min.
Alternative scenes: 8

The process of the scenes is identical, but in the Extended Cut, the women at the table are topless - in the Director's cut, they're dressed. Furthermore, you can make out the landlord trying to pull one of the men's feet off the table in the Extended Cut.

The short runtime difference (1 sec.) in the passed three scenes is being compensated by a slightly longer/slower outside-view during the night.

In the Export Cut, the woman is topless and Marshall puts his left hand on her left breast. After Hopkins wakes him up by kicking him, he pushes the woman away, gets up and quickly steps outside to hurl. Subsequently, he returns and sits down again. The process is the same in the Director's Cut, but the woman is dressed and there was a different take used for the described part (well noticeable due to Hopkins' viewing direction). Also, the woman is a different one. The Export Cut is about 1.5 seconds shorter because of the scene's shorter beginning.

Hopkins gets up and walks to the right. There was another take used here. In the following scene, the lady at the table is topless in three following scenes, dressed in the Director's Cut. Just like before, there is a different woman shown in the Director's Cut.

The black screen at the end of the film is slightly longer in the Export Cut to even the runtimes again.
