Mel Gibson has been caught up in a new rant controversy after telling an Central American Studies professor to "f**k off" during a tense press conference. The movie mogul, who made headlines last summer (06) for anti-Semitic comments he made during a drink driving arrest, was addressing a film class at Cal State University at Northridge last night (22MAR07) when the professor questioned the accuracy of his APOCALYPTO film. ALICIA ESTRADA asked Gibson if he had read about the Mayan culture before shooting the controversial film, suggesting that some of the bloodthirsty, sacrificial scenes in the film were both wrong and racist. According to website TMZ.com, Gibson suddenly exploded in anger, responding, "Lady, f**k off." Gibson also became angry when members of the Mayan community protested on how they were portrayed in the film during the lecture. They were escorted out of the room.
