"For all my lovely folks asking me for the past 2 years... YES... Just started shooting my next Tamil and Hindi film. Wish me luck. It's 'Irrudhi Suttru' (Final Round) in Tamil and 'Saala Khadoos' in Hindi," posted Madhavan on his Twitter page.
Madhavan plays a retired boxer-turned-coach in the film, which is being directed by Sudha Kongara, former associate of filmmaker Mani Ratnam.
He had also undergone a crash course in boxing.
Madhavan was last seen in the 2012 films "Vettai" and "Jodi Breakers".
