Semitic charges at Mel Gibson © Pool New / Reuters / REUTERS It turns out Mel Gibson's movie about biblical Jewish hero Judah Maccabee has hit a bit of a snag. "You hate Jews," "Basic Instinct" and "Showgirls" scribe Joe Eszterhas, tasked with writing the since-rejected screenplay for Gibson's latest passion project, accuses the reputation-challenged star in a memo obtained by the Wrap. In the nine-page letter, Eszterhas states that Gibson pitched the "The Maccabees" solely "to deflect continuing charges of anti-Semitism which have dogged (him), charges which have crippled (his) career," and then made anti-Semitic remarks throughout the writing process. Not surprisingly, Gibson fired back just hours later, calling Eszterhas' claims "utter fabrications."

I was very frustrated that when you arrived at my home at the expense of both Warner Brothers and myself you hadn't written a single word of a script or even an outline after 15 months of research, meetings, discussions and the outpouring of my heartfelt vision for this story.

I absolutely want to make this movie; it's just that neither Warner Brothers nor I want to make this movie based on your script. The actor-director maintained that both he and the studio were "extremely disappointed" with Eszterhas' draft -- which Eszterhas claims he spent two years researching and writing.

The writer, who also penned the war-crimes trial drama "The Music Box," is asking Gibson to return his script, which could be shopped elsewhere since Warner Bros. rejected it. But all is not lost.
