Its known fact that Aamir Khan leaves no stone unturned to play any given screen character to perfection. And with Rajkumar Hirani’s upcoming film ‘P.K.’ the perfectionist is trying his best to be authentic.

Now, we’ve been informed that the actor has been busy taking lessons in Bhojpuri as his character will be required to speak the language.

Revealed a source close to the film, "Aamir has been trying to master Bhojpuri for the last four months. Everyone is wondering why he has been learning a language that is traditionally spoken in east Uttar Pradesh and Bihar, when the film has largely been shot in Rajasthan." This is a new twist to the tale. There is a lot of curiosity as to what the film is about.

Interestingly, this isn’t the first time Aamir has taken lessons to learn a language for a role. While he was preparing for his part in Ashutosh Gowariker’s movie, ‘Lagaan’ (2001), he had learnt to speak Awadhi.

Meanwhile, the source informs us that this entire year, the actor and the makers will be busy travelling to Rajasthan and back to Mumbai, finishing the shooting schedule of ‘P.K’.

The film, which marks the reunion of the 3 Idiots (2009) team - Vidhu Vinod Chopra (producer), Rajkumar Hirani (director) and Aamir - is expected to release next year.
