Director: Rajkumar Hirani
Stars: Aamir Khan, Anushka Sharma, Sanjay Dutt
Plot: A stranger in the city asks questions no one has asked before. His childlike curiosity will take him on a journey of love, laughter, and letting go.
Aamir Khan got nude for the first time in his career for this film.
Aamir Khan had planned a special screening of the film for his friend Sanjay Dutt in jail.
In 2011, in its initial scripting stage, Rajkumar Hirani named the film 'Talli' then changed it to 'Ek Tha Talli' (a title which he actually loved) but later on came to know that 'Ek Tha Tiger' was already in production which was releasing in 2012. So he dropped the idea and after many titles, he came up with a unique title which only had initials, 'P.K'.
PK is the first film of Aamir Khan and Sanjay Dutt together. In the early 90s they were supposed to do the film Sahabzaade (1992) together but Aamir left the film and the role went to Aditya Pancholi.
Apparently, for every take, Aamir had to eat a fresh paan to fill his mouth, also before beginning the shoot Aamir would eat at least 10-15 paans to get the right color inside his mouth and on his lips.
The Supreme Court of India rejected the plea made by some Hindu Groups to ban PK by stating, "Do not waste the valuable time of Court by applying stupid logic".
PK is the highest grossing Hindi film in China
Poster release of PK featuring nude Aamir Khan with his private parts being hidden by only a Transistor he held in his hands, sparked controversy leading to demand for ban on the release of the film.
In the climax, when Tapasvi Maharaj challenges P.K. on the talk show, P.K. replies with 'Sarat manjur hai" to accept it. This is a clear nod to Aamir Khan's film Lagaan (2001) where Bhuvan, the character played by Aamir Khan says the same to the British officer challenging him to a cricket match.
Boman Irani is the only actor to have starred in every one of Rajkumar Hirani's films.(Munnabhai MBBS,Lage Raho Munnabhai,3 Idiots & PK).
Shah Rukh Khan was offered the cameo role of the second alien (that was played by Ranbir Kapoor) at the end of the film but declined. He actually also was in consideration for the role of Sarfraz Yousuf, but director Rajkumar Hirani decided against casting him since he wanted a younger actor to play that role. Sushant Singh Rajput was then selected.
Arshad Warsi who played the popular role of Circuit in Munna Bhai M.B.B.S (2003) was offered a role in the film but declined.
Initially Rajkumar Hirani wrote the script with Ranbir Kapoor in mind for the leading role. But after working with Aamir in his previous film 3 Idiots(2009) decided to offer the lead role to him.
Anushka Sharma did not cut her hair but wore a wig for the film.
For the character of PK, Khan popped his ears out and wore green contact lenses. The director was nervous about the changes but Aamir assured him that it would add to the mystery of the character.
Aamir Khan does not blink in the film,
When the shoot of the film was going on in Chandni Chowk area of Delhi, an FIR was lodged against makers of the film for allegedly hurting religious sentiments in October 2013. The objection was regarding a scene in the film where a man dressed as the Hindu deity, Lord Shiva pulls the rickshaw with two burqa clad women as passengers
