PK is a 2014 Indian Hindi-language science fiction satirical comedy drama film edited and directed by Rajkumar Hirani and written by Hirani and Abhijat Joshi and jointly produced by Hirani and Vidhu Vinod Chopra under the production banners of Rajkumar Hirani Films and Vinod Chopra Films, respectively. The film stars an ensemble cast of Aamir Khan, Anushka Sharma, Sushant Singh Rajput, Boman Irani, Saurabh Shukla and Sanjay Dutt.
After the success of 3 Idiots, Hirani and Joshi began scripting their next project; finding similarities with the plot of Inception, they scrapped the film. It was later rewritten with a different angle and tone. During production, the film was initially titled Talli and later Ek Tha Talli before being changed to PK as the latter title was found to be too similar to Ek Tha Tiger. The film's soundtrack was composed by Shantanu Moitra, Ajay–Atul and Ankit Tiwari with lyrics written by Swanand Kirkire, Amitabh Varma and Manoj Muntashir. UTV Motion Pictures acquired the distribution rights of the film. PK was the first Bollywood film to be shot in Belgium.
PK was released on 19 December 2014.
