Kalanithi hasn't escaped the politics of vendetta that unfolds in Tamil Nadu after every regime change. In June 2011, a month after AIADMK came back to power, nine cases, most of them related to cheating and intimidation, were filed against Sun Pictures and its then COO, Hansraj Saxena. As a result, Saxena spent almost two months in police custody. Saxena was a part of the founding team of Sun TV and was known to be close to Kalanithi. He inexplicably resigned from Sun Pictures in September 2011 and launched his own company called Sax Pictures and produced two films.
On December 17, 2012, Saxena, along with film distributor R Ayappan, lodged a police complaint against Kalanithi and other senior Sun functionaries. According to Saxena, Kalanithi has been avoiding him for almost one-and-a-half years for no reason. "He had alleged that both of us [Saxena and Ayappan] were the ones who cheated, so I decided to quit," says he. Saxena next wants to start a film channel that will compete with Sun's KTV.
Controversies have chased Dayanidhi too. In New Delhi, unlike other Tamil Nadu politicians who only wear veshti and white shirt as some sort of political uniform, Dayanidhi would dress crisply like a business leader. He would be Karunanidhi's mediator whenever he met Prime Minister Manmohan Singh or UPA Chairperson Sonia Gandhi in New Delhi. He was instrumental in getting Bill Gates to Chennai to meet Karunanidhi in December 2005, though the DMK patriarch was out of power at that time.
