OK, you might think that looking at naked woman swimming around underwater, more like underwater dancing, to light jazz porn music would be sexy. Not especially, even with the oddly colored bright face decorations. It suppose it could be used as a DVD background scene decoration in a very liberal home or office.
You can stream trailers - oops not working, and find and look at some pictures. Did I mention this is a German film? It does look like they had some fun making it.
Here is another location for the making of video.
I saw this for sale at Fry's and Amazon.
