The film industry is demanding an international investigation into alleged war crimes against Tamils in the Asian nation.
Southern superstar Kamal Haasan might join the protest, reports said.
The protest is taking place on the premises of South Indian Film Artists' Association here.
"All of us have come here to protest against what is happening to our brothers and sisters in Sri Lanka. This is to say equal status has to be given to Tamils in Sri Lanka. If not give them a state," Tamil actor Prakash Raj told CNN-IBN.
"Also we need to bring to book the culprits who have continuously been part of genocide and human killings. They need to be booked and punished," Prakash Raj said.
Amid growing political disputes in the Indian political paradigm over the issue of SriLankan Tamils, the Tamil Nadu Assembly last Wednesday adopted a resolution that asked the Centre to stop treating Sri Lanka as a friendly nation,reports said.
The resolution was passed by Tamil Nadu Chief Minister and All India Anna Dravida Munnetra Kazhagam (AIADMK) supremo J Jayalalithaa.
The resolution, that was unanimously adopted by the state Assembly, also demanded the Centre to impose an economic embargo against the Asian nation till alleged atrocities against Tamils are ended.
The Dravida Munnetra Kazhagam (DMK) last month pulled out of the Congress-led United Progressive Alliance (UPA) government Sri Lanka issue.
