Biopics on sport personalities took Bollywood by storm. Latest buzz is after Priyanka Chopra and Farhan Akhtar, Salman Khan has joined the league.

The actor will pack a punch as he will be soon playing a 40-years-old onscreen boxer in Ali Abbas Zafar's next.

Titled as 'Sultan' the film is based on the sport boxing. A source says, "In Sultan, Salman plays the title role of a 40-year-old boxer. It’d require a huge amount of preparation. Salman would have to change his entire physique and body language. It’d entail many months of a strict exercise regime and a new diet control so he can acquire a boxer’s body. With his heavy commitments, Salman is not sure how he will be able to give Sultan the time, attention and single-minded focus it requires."

If everything goes well, then the film will likely hit the screens in 2016.
