Mukkabaaz (English: The Brawler; Hindi pronunciation: [mʊkkaːbaːz]) is a 2017 Indian sports drama film co-written, co-produced and directed by Anurag Kashyap. Jointly produced by Aanand L. Rai under his label Colour Yellow Productions and Phantom Films, the film stars Vineet Kumar Singh, debutant Zoya Hussain, Ravi Kishan and Jimmy Shergill in the lead roles. It follows Shravan Kumar (Singh), an aspiring boxer, who falls in love with the niece of the boxing federation head, Bhagwan Das Mishra (Shergill). Kashyap, Singh, Mukti Singh Srinet, K.D.Satyam, Ranjan Chandel and Prasoon Mishra wrote the script. Aarti Bajaj and Ankit Bidyadhar edited the film, while Shanker Raman, Rajeev Ravi and Jayesh Nair served as the directors of photography.
Mukkabaaz was conceived by Singh, who wrote it with his sister Mukti Singh, based on his observations of several sportspersons' experiences in India. Several producers rejected it until Kashyap agreed to make the film if Singh would become a real boxer. To prepare, Singh went to the Netaji Subhas National Institute of Sports, where he trained in boxing for a year. Hussain learned non-verbal communication from a sign language expert for her role.
Mukkabaaz premiered in the Special Presentations section at the 2017 Toronto International Film Festival and was also screened at the 2017 Mumbai Film Festival. It was released theatrically in India on 12 January 2018 and received mostly positive reviews, with particular praise for Singh's performance. The film grossed ₹10.51 crore (US$1.5 million) at the box office.
