While the actor has learnt a bit of Urdu before, he is currently brushing up on his skills to play a Muslim gangster in the sequel to the 2007 hit. Apparently, he's trying to get the finer nuances of it right.
Since he's playing a Muslim character for the first time in his career, he wants to get everything from the pronunciations to the body language spot on. Interestingly, he's learning Marathi for another movie. Hmm... a linguist in the making?
