LOS ANGELES -- Screenwriter Joe Eszterhas has released an audiotape of Mel Gibson recorded at the actor's home in Costa Rica in December, according to TheWrap.
On the recording, obtained by TheWrap, Gibson can be heard screaming epithets at his house guests, including vicious verbal attacks on his ex-girlfriend, Oksana Grigorieva.
"What the f**k have you been doing!!" Gibson screams.
Eszterhas says he released the audiotape after Gibson accused him of lying about his alleged hate-filled rants.
Gibson is now seriously considering suing Eszterhas, TMZ reports.
The website, citing sources close to the actor, says Gibson believes he has "a basic human right" not to be secretly recorded in his own home.
Gibson's people are reportedly looking at the laws of Costa Rica to determine if recording laws were violated.
They are also trying to determine if Gibson's privacy was violated by the release of the audio.
Earlier this month, Eszterhas recounted numerous alleged incidents in detail in a nine-page letter to Gibson, published by TheWrap.
In the letter, Eszterhas insists he worked diligently on his script for 'The Maccabees.'
He writes, "I've come to the conclusion that the reason you won't make 'The Maccabees' is the ugliest possible one. You hate Jews."
Eszterhas also recounts Gibson repeatedly using derogatory epithets for Jewish people.
In a letter replying to Eszterhas, Gibson denied the allegations, saying most of the claims were fabricated.
Gibson's letter said Eszterhas "only had a problem with me after Warner Brothers rejected your (Eszterhas') script."
Gibson, in his five-paragraph response, said he wouldn't respond "line by line," and that the decision not to proceed with Eszterhas "was based on the quality of your script, not on any other factor."
Warner Bros. has put the controversial Maccabees project on hold, the company said.
"We are analyzing what to do with the project," said spokesman Paul McGuire.
Allegations of anti-Semitism are nothing new for Gibson.
