Over the last few weeks the Czech papers have been full of a man called Robert Rosenberg, and a rather unusual film project. Rosenberg is a porn star turned producer, and two weeks ago the Czech tabloid Super claimed he was planning to make a hard-core sex film in the former Terezin concentration camp. The paper even superimposed images of people indulging in graphic sex acts over pictures of the fortress's grim red-brick walls, to help those readers with little or no imagination. Unsurprisingly the report caused uproar - around 140,000 Jews from across Europe were herded into the Terezin ghetto, thousands died there, and almost 90,000 were later sent to Auschwitz.
