Krishna is an tamil actor, his father is film producer Kulasekaran (Pattiyal Sekar) and his brother is noted film director, Vishnuvardhan. He went to St. Bede's Anglo Indian Higher Secondary School in Chennai, studied at Loyola College and graduated in MBA finance in USA. He worked for a year-and-a-half in the IT industry and started his own business that was doing well. He has also undergone training in Jazz and worked as a dancer/choreographer before he left for US.
He first faced the camera for Mani Ratnam's Anjali and later appeared in Iruvar and Santosh Sivan's The Terrorist. He was also chosen to play the younger version of Rajinikanth's character in Thalapathi, but the character was later scrapped because it affected the film's length.
He played his first lead role in Ali Baba, which was produced by his father. The film met with favourable reviews, but was not a commercial success. After his first film, he wanted to do a gangster film based on a true incident in North Madras, called Madras to be directed by Five Star Krishna, but it was shelved because of misunderstandings between the director and the producer. His next two films Kattradhu Kalavu and Kazhugu were also produced by his father. In Kazhugu he played someone who recovers bodies of suicide victims who jump off a cliff. It received positive response.
Now he is busy with Vanavarayan Vallavarayan, Vallinam (Cameo Appearance), Vizhithiru, Illa Aanalum Irukku and Vanmam.
