"We would have hoped that Warner Bros could have found someone better than Mel Gibson to direct or perhaps even star in a film on the life of the Jewish historical icon Judah Maccabee," Abraham Foxman, national director of the Anti-Defamation League, said in a statement.
"As a hero of the Jewish people and a universal hero in the struggle for religious liberty, Judah Maccabee deserves better."
Rabbi Marvin Hier, dean and founder of the Simon Wiesenthal Center, said: "Casting him (Gibson) as a director or perhaps as the star of (a film about) Judah Maccabee is like casting (Bernard) Madoff to be the head of the Securities and Exchange Commission, or a white supremacist as trying to portray Martin Luther King Jr. It's simply an insult to Jews."
The American Gathering of Holocaust Survivors and their Descendants said: "Holocaust survivors are aghast that a major Hollywood studio would join with Mel Gibson in this venture and view it as an affront to all victims of anti-Semitism, intolerance, and sexism."
Nierob declined to respond to the backlash from Jewish leaders. Warner Bros had not responded by Friday afternoon to a request for comment on the project itself or the negative reaction it has drawn.
Gibson, the Oscar-winning director of Braveheart, has defended himself against accusations of anti-Semitism ever since his 2006 drunken driving arrest, in which a deputy's report revealed Gibson made Jewish and sexist slurs while in custody.
Last month, he reached a US$750,000 (NZ$908,000) settlement with his ex-girlfriend, Russian musician Oksana Grigorieva, and agreed to continue providing housing and financial support for their young daughter to resolve a bitter legal fight that followed sexist, racist rants attributed to the actor.
His last project was The Beaver, a drama in which he starred opposite director Jodie Foster as a man who sinks into such a deep depression, he can only communicate through a beaver hand puppet.
Gibson earned strong reviews for his performance but the film itself only made about $6.4 million worldwide.
