LATEST: Controversial film director Mel Gibson has been attacked by a leading Holocaust expert after announcing plans to produce a film about the terrible genocide.

The LETHAL WEAPON star, who caused outrage from critics who claimed his movie PASSION OF THE CHRIST contained elements of anti-Semitism, will centre the story on Dutch Jew FLORY VAN BEEK, whose non-Jewish boyfriend hid her from the Nazis.

Gibson's father HUTTON GIBSON has openly stated he doesn't believe the Holocaust ever took place.

RAFAEL MEDOFF, director of the David Wyman Institute for Holocaust Studies, says, "For (Gibson) to be associated with this movie is cause for concern.

"He needs to come clean that he repudiates Holocaust denial, and that he understands the Holocaust was not just another atrocity that occurred in the Second World War along with other atrocities."
