Vettai

Vettai (transl. Hunt) is a 2012 Indian Tamil-language action comedy film co-produced, written and directed by N. Lingusamy. The film stars Arya and R. Madhavan in the lead roles, while Sameera Reddy, Amala Paul, Ashutosh Rana, Nassar and Thambi Ramaiah appear in supporting roles. The story follows Guru Murthy (Madhavan), a timid and peace-loving constable who lacks confidence, and his younger brother Guna (Arya), a bold, aggressive and fearless policeman. Despite being less capable in the field, Guru often gets credit for arrests, while Guna does the real work behind the scenes.
