If this is true, then Mel Gibson is crazier than anyone ever realized

Basic Instinct screenwriter Joe Eszterhas, once the highest paid screenwriter in the world, and Mel Gibson, who once wasn't thought of as the craziest person in Hollywood, are embroiled in a very public spat.

Gibson has decided not to proceed with Eszterhas' script for The Maccabees, the story of the biblical hero Judah Maccabee and the Jewish revolt against the Syrian Greeks. Eszterhas says the reason is because Gibson hates Jews and the project was just a smokescreen. Gibson says the project is on hold because Eszterhas' script sucks.

Where things get really weird is the 8 page letter Eszterhas made public through the Hollywood gossip site The Wrap, in which he alleges aside from Gibson being a crazed anti-Semite, he is prone to hysterical, uncontrolled outbursts of anger that seem mild compared to the South Park parody of the Braveheart star.

Among other claims made by Eszterhas, Gibson blurted out things like (in reference to ex-girlfriend Oksana Grigorieva) "I want to f**k her in the a** and stab her to death while I'm doing it." and plenty more
