Aamir Khan is an alien in the film 'PK'Facebook/PK The Film

Aamir Khan's satirical film "PK" will soon hit the theatres and the actor is leaving no stone unturned to promote his film.

"PK" is touted as the biggest release of this year and has created tremendous buzz ever since Khan's nude poster was released, and to keep the merriment going, the makers have been releasing the dialogue promos of the film.

However, Khan's character in the film is still not known. While, the buzz is that the actor is playing the role of an alien, some viewers think that Khan plays an autistic person in the film.

But the latest dialogue promo reveals a complete different plot of the film. In the promo, the "Dhoom 3" actor is seen saying that he is an astronaut.

The dialogue promo has the lead actress of the film, Anushka Sharma interviewing Khan about his profession. Khan, promptly replies that he is an astronaut who has travelled to the moon.

"PK" is directed by Rajkumar Hirani of "3 Idiots" and "Munna Bhai" series fame, and produced by Hirani, Vidhu Vinod Chopra and Siddharth Roy Kapur.

Apart from the lead actors, Khan and Sharma, "PK" also features Sushant Singh Rajput, Saurabh Shukla, Boman Irani and Sanjay Dutt in pivotal roles.

The film, apparently, revolves around how an alien lands on Earth and puts on several avatars in order to survive on the planet. The 48-year-old is said to be playing a dual role, as an alien and God.

But, with the new promo, it appears like the viewers will have to wait until "PK" releases worldwide on 19 December, to find out the "real" character of Mr Perfectionist.
