Not many know that the makers of 'PK' kept on delaying the film as they couldn't find an apt title for it.

It is said that before finalising the title 'PK', Rajkumar Hirani experimented with three different titles.

A source suggests, "It was initially called Ek Tha Talli but was changed to just Talli as around that time, Salman Khan's Ek Tha Tiger had released.Then it was renamed as Peekay before Hirani decided to stick to PK."

Inspite of having a title which means drunk, the film won't have any anti-drinking warnings, as Aamir Khan is completely in disagreement with the Censor Board to insert such warning.
