Vangaveeti Radhakrishna, son of late Congress MLA Vangaveeti Mohana Ranga, asked a Vijayawada court on Wednesday, to take legal action against filmmaker Ram Gopal Varma.
"Both my uncle and father had lost their lives fighting for the poor. RGV took our surname Vangaveeti as his film title and created a hyperbole which is nowhere connected to our family legacy . He portrayed our father as a villain," Radhakrishna was quoted as saying.
The court was hearing a a criminal defamation case against the makers of the film.
"Vangaveeti" was said to be the biopic of Vangaveeti Mohana Ranga, a leader of the Congress party, who belonged to the Kapu community, and was murdered in 1988 when he was on a hunger strike.
The murder set off unprecedented violence in Vijayawada and other parts of the Krishna district as well as neighbouring ones.
The violence abated after then Andhra Pradesh Chief Minister NT Rama Rao made his Telugu Desam Party (TDP) legislator Devineni 'Nehru' Rajasekhar surrender. Then Home Minister Kodela Sivaprasada Rao also had to resign.
The film was facing controversy from the date of its announcement.
Ranga's followers suspect that RGV has portrayed their leader in a bad light. They have also raised objections to using his surname for the film.
During the film's release, Radhakrishna had also met the Director General of Police (DGP) of Andhra Pradesh, and voiced his objections, by registering a police complaint.
Ahead of the filmâ€™s release, Varma also met with Rangaâ€™s family, including Radha Krishna, and later drove to the residence of â€˜Nehruâ€™, to discuss the row.
The director had also clarified that the film was not against any caste and that apprehensions of violence were unfounded.
