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 become 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 seafilming for almost 120 days, with many of the actors getting sea sickness.
