Mel Gibson is often attacked for his alleged anti-Semitic ways, but a scathing new letter from famous screenwriter Joe Eszterhas makes him seem like a maniac!

Joe, 67, was the screenwriter for the scrapped movie The Maccabees, a film based on Jewish biblical hero Judah Maccabee. Mel, 56, was slated to direct, but now Joe is alleging in an open letter obtained by TheWrap.com that he killed the project personally.

“I’ve come to the conclusion that the reason you won’t make The Maccabees is the ugliest possible one. You hate Jews,” he wrote. “You continually called Jews ‘Hebes’ and ‘oven-dodgers’ and ‘Jewboys.’ It seemed that most times when we discussed someone, you asked ‘He’s a Hebe, isn’t he?’ You said most ‘gatekeepers’ of American companies were ‘Hebes’ who ‘controlled their bosses.’ You said the Holocaust was ‘mostly a lot of horses–t.’”

Joe also alleged that the only reason Mel wanted to make the movie was to “convert the Jews to Christianity.”

Also shocking are Joe’s allegations about Mel’s attitude toward his ex-girlfriend Oksana Grigorieva.

“You were raving at Oksana even after you’d reached a custody agreement over [their daughter] Luci,” he wrote. “And then you were even more explicit about your threat: ‘I’m going to kill her! I’m going to have her killed!’ You said you’d become friends with two FBI agents (or former FBI agents) and they were going to help you to kill her.”

Mel quickly issued a letter in response, which blamed the failure of the movie on Joe, TMZ reports.

“I will say that the great majority of the facts as well as the statements and actions attributed to me in your letter are utter fabrications,” he wrote. “Not only was the script delivered later than you promised, both Warner Brothers and I were extraordinarily disappointed with the draft. In 25 years of script development I have never seen a more substandard first draft or a more significant waste of time.”

Are YOU shocked by these allegations, HollywoodLifers?
