We did a double take when we saw this picture of Emraan Hashmi's [ Images ] impressive pecs for director Milan Luthria's new film, Once Upon A Time in Mumbai [ Images ].

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 [ Images ]. 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 [ Images ] and Prachi Desai [ Images ], is expected to be out in May or June.
