Seems like Emraan is hellbent on giving himself and the character he is playing a makeover.
Emraan plays a toughie in the movie, who challenges an underwold don played by Ajay Devgn. To get the look right, the actor underwent three months strict exercise and diet regime.
Once Upon A Time in Mumbai, which also stars Kangna Ranaut and Prachi Desai, is expected to be out in May or June.
