Ravana Desam
Ravana Desam, or Ravan Desam, is a Tamil film written and directed by Ajay Nuthakki. The film is based on the refugees missing during the 2009 Sri Lankan Civil War.
Nuthakki spent almost four years on the film, with two years dedicated to research to get the facts right. Nuthakki stated that Even though my film is based on true events, I have built the premise on a very simple theme that humans are still animals and are likely to go extinct soon. What happened in Sri Lanka in 2009 was described by the United Nations as a bloodbath. He said that the time he invested in working on the film was worth it. The cast and crew for the production were on the sea filming for almost 120 days, with many of the actors getting sea sickness.
