Actor Mel Gibson's attorneys have accused the producer of American-Irish drama film "The Professor and the Madman" of seeking to swindle Irelands tax authorities. Gibson is engaged in a legal battle with producer Voltage Pictures over the film, which tells the dark origin story of the Oxford English Dictionary, reports variety.com.

The director, Farhad Safinia, first accused Voltage in July of trying to inflate expenses on the film, which would result in a larger tax rebate from the Irish government. Gibson, who co-produced and starred in the film as lexicographer James Murray, filed an answer to a cross-complaint on Wednesday, in which he joined in the accusation.
