Everything about PK has been a top secret. The makers have decided against the idea of revealing anything about the character that Aamir Khan plays.
However, a leading daily has confirmed through their sources that Aamir’s character in the film is named Punmiya Kushal (full form of PK).
Unusual and quirky character names have always been a part of Rajkumar Hirani films, and PK will be no different. In 3 Idiots, Hirani’s characters were names Ranchordas Shyamaldas Chanchad (Rancho), Chatur Ramalingam (Silencer). In fact, even Anushka Sharma in PK is named Jagat Janani.
