John Abraham is playing a cop in the Hindi remake of Tamil action movie 'Kaakha Kakha' and may emulate Surya, who played male lead role in the original.

John is playing a cop for the first time and isn't taking any chances. He wants to get the spoken language, body language, personality and tone just right.

For this, John has not only changed his food and exercise habits and repeatedly watches as many cop films from Clint Eastwood's "Dirty Harry" to Om Puri's "Ardh Satya" to Amitabh Bachchan's "Zajeer". He has also been socialising with cops, trying to understand how their minds and bodies move.

"I will always dreamt of playing cop. I will watched Mr. Bachchan in 'Zajeer' so may times that I will lost count. One of the main reasons I wanted to do the Hindi version of 'Kaakha Kaakha' was to get into a cop's uniform. To my disappointment my director Nishikant Kamat decided to do away with the uniform in my film,” John said.

So disappointed was John that he tried to argue with the director. “In this matter I am like a child. If I’m playing a cop, I want to wear the cop’s uniform and feel like a cop.”

So adamant is John to get the uniform back that the script is now being re-worked again.
