Source close to the team revealed: "Emraan will go bare body for one of the scenes in the film. He has been maintaining himself really well to take his shirt off for the scene."
"In 'Ghanchakkar', he will show his agile self in several scenes," the source added.
The 33-year-old is known for locking lips with his co-stars in films like "Murder" and "Zeher".
Apparently there is a train sequence in which Emraan exhibits extraordinary fitness to carry off stunts inside a moving train.
Directed by Rajkumar Gupta, "Ghanchakkar" features Vidya Balan in the female lead and it is slated for a June 21 release.
