Visaranai (transl. Interrogation ) is a 2016 Indian Tamil-language crime drama film written and directed by Vetrimaaran. It is based on the novel Lock Up by M. Chandrakumar. The film stars Dinesh, Anandhi, Samuthirakani, Aadukalam Murugadoss, Kishore, Pradheesh Raj, and Silambarasan Rathnasamy. The film deals with lives of two men before and after thrown into a kafkaesque scenario in which they get tortured for confession. Vetrimaaran later told that, in the beating sequences in film, the actors were really beaten (which was criticized by some of the foreign media and a member of Golden Globes during the film's Oscar campaign), and all of them had to undergo counselling sessions.The film premiered in the Orrizonti (Horizons) section of the 72nd Venice Film Festival, where it won the Amnesty International Italia Award. The film was released in India on 5 February 2016 and received highly positive reviews from both critics and audience alike. Many issues arose regarding the film in Tamil Nadu among the police force. At the 63rd National Film Awards, the film won three honours: Best Feature Film in Tamil, Best Supporting Actor for Samuthirakani and Best Editing for Kishore Te. It was selected as India's official entry for the Best Foreign Language Film at the 89th Academy Awards but it was not nominated. At the 64th Filmfare Awards South, the film was nominated for the Best Film, Best Director for Vetrimaaran and won the award for the Best Supporting Actor for Samuthirakani.
