Actor Emraan Hashmi, who has been experimenting with his looks, is in a dilemma as for his upcoming film Ghanchakkar and Karan Johar's flick he has to constantly gain and lose weight. In Rajkumar Gupta's Ghanchakkar, Emraan plays the role of a conman, who is an expert at breaking locks. He will be seen opposite Vidya Balan. Presently Emraan is shooting for Ghanchakkar, for which he has to sport two different looks. While one requires him to be muscular and beefed-up, in the other one he has to be lean.

"I have two very distinct looks for Ghanchakkar and Ungli (Karan Johar's film). Simultaneously I am in the middle of promoting Raaz 3, so it's quite a challenging task, to juggle between the looks without affecting either of the schedules," Emraan said. Earlier the actor had gained muscles but now the director wants him to lose some of it for the next crucial schedule. Once Emraan is done with shooting for Ghanchakkar, will have to start gaining muscles soon for Karan Johar's tentatively titled film Ungli, where he has to sport a bulky frame.
