Mary Kom is a 2014 Indian biographical sports film directed by Omung Kumar and produced by Sanjay Leela Bhansali in association with Viacom 18 Motion Pictures. The film stars Priyanka Chopra in the lead role of the eponymous boxer, with Darshan Kumar and Sunil Thapa in supporting roles of her husband and mentor, respectively. Mary Kom depicts Kom's journey of becoming a boxer to her victory at the 2008 World Boxing Championships in Ningbo. The film marks the Hindi playback singing debut of Chopra, who provided her vocals for a song named "Chaoro" (a lullaby). Mary Kom was developed by writer Saiwyn Quadras, who suggested the storyline to Kumar when Kom was not a familiar name in India despite her numerous achievements. Kumar met Kom to ask her permission for the film, before her bronze medal victory at the 2012 Summer Olympics, which brought her recognition. Chopra underwent extensive physical training for three months to attain a muscular physique and learned Kom's distinct boxing style. Principal photography started in June 2013 at Filmistan Studio, where the boxing sequences were filmed. After plans to shoot in Kom's hometown, Manipur, were dropped due to safety concerns, Mary Komwas shot in Dharamshala and Manali, where a major portion of Manipur was recreated.
