Buzz is that Anushka Sharma is playing double role in the film PK – one of a reporter and the other character is of a prostitute. The posters definitely have indications. The pose, the stereo, railway track and Aamir and Anushka's mad expression is making confusions.
Some reports suggest that Aamir Khan is an alien in the movie, he is playing double role in the movie but the actor himself said that his character is not of that type. Aamir Khan tweeted on the guess about his character in film PK: "Alien! Adi Manav! Drunkard! Just someone who has lost his clothes! Ha ha ha!!! Interesting guesses!!!"
Aamir Khan is a mentally challenged person in film PK
So, Aamir Khan is not an alien, adi manav or drunkard in film PK. From all the released posters we can guess that Aamir Khan may be a mentally challenged guy with God gifted power in film PK. Another guess is that Aamir Khan is playing two shades of a human whose one shade is full of abnormality.
Let’s wait till 19 December as no guess is working.
