Mahesh Bhatt loves a new challenge. It has been the curve of his life and career and we have learnt that the producer-director will debut as a singer in Emraan Hashmi starrer 3D thriller Mr X! Mahesh will be singing a song titled You Can Call Me X and the song is so catchy that the makers are planning to shoot a music video with Emraan and Amyra Dastur.

Mahesh Bhatt confirms, "Music is an inseparable part of me. And every time before we record a song first I sing it. I was doing the same for Mr. X when Jeet's eyes shone up like a child who had found a rare gift. He said, you are going to do it. I didn't see a reason, why not! Perhaps the song was made for me."

Director Vikram adds, "We were in a music sitting when Jeet Ganguli was making us hear this song for the first time there was me, there was Bhatt Saab, Mukeshji and of course we liked the song, and what happened is that Jeet said that itna female voice hoga and then you can call me X will be in a male voice so Bhatt saab said give me the paper let me sing the male voice so when he sang it, it just sounded right and then who ever sang it after that didn`t sound right enough so we told Bhatt sir you should."

Emraan Hashmi plays a person who is forced to become a vigilante after he was tried to be murdered. A good cop, Emraan gets entangled into a treacherous scheme and is left to die in a chemical factory by people who blow it up with the intention to kill him. However, as fate would have it, the chemicals in the factory does not kill him but cause a reaction that turns Emraan invisible! He decides to take revenge on those who are not only responsible for his state but are also hatching a devious, evil plan. He becomes the man who is not afraid to break the law because he wants to protect it. Also starring the gorgeous Amyra Dastur, the film has everything that an Emraan Hashmi blockbuster would have - great songs, a sizzling new pairing and not to forget the serial kisser is doing what he does best and that too when invisible!
