Aamir Khan's is an excellent marketer of his films. This time he is out to spread the word about his forthcoming film PK which is set to hit the theatres on December 19. The huge promotional drive for PK has generated a lot of interest among the viewers and they would be expecting a lot of things from the film. Here is a list of five such things.Aamir Khan: Of course, he is the best bait for the audience. He has separated himself from the numbers game and that prompted him to do films he really wants to do.
