Is Raju’s PK inspired by Frost/Nixon?

Speculation is rife that the Aamir Khan-Raju Hirani’s political satire PK could have shades of the Oscar nominated Frank Langella-Michael Sheen film Frost/Nixon (2008).
But of course it will be aligned to Indian politics as against the Watergate scandal that the original threw light on. Raju’s film will also make room for a leading lady and some song-n-dance sequences that are Bollywood’s commercial format mainstay.
One hears that the film-maker’s ideal wish-list includes actors Aamir and Sharman Joshi for the roles of the journalist and the politician; Kareena Kapoor is hoping to be the female protagonist. Earlier, Aamir had said, “I don’t know anything about the film. I don’t even know if I am in it yet.”
The official spokesperson for PK said, “Nothing is known about the project. Raju sir hasn’t opened his cards to anyone; not even to his producer Vidhu Vinod Chopra.”
It is being said that Bollywood’s most respected director is still working on the final draft of PK and he will give Vinod Chopra and Aamir a narration when he is ready. However, the source who hinted to us that Raju’s next is a political satire says, “Since Raju’s film is the most awaited announcement, Naaz Building (Bollywood’s stock exchange) is full of rumours on what it could be. Everything around the project is definitely hush-hush, but one cannot discount any rumour.”
