PK is a 2014 Indian satirical comedy-drama film directed by Rajkumar Hirani and written by Hirani and Abhijat Joshi. It was jointly produced by Hirani and Vidhu Vinod Chopra under the banners Rajkumar Hirani Films and Vinod Chopra Films respectively. The film follows an alien who comes to Earth on a research mission, but loses his remote to a thief, who later sells it to a godman. He befriends a television journalist and in his quest to retrieve the remote, questions religious dogmas and superstitions. The film stars Aamir Khan in the titular role with Anushka Sharma, Sushant Singh Rajput, Boman Irani, Saurabh Shukla and Sanjay Dutt in pivotal roles.
The film centres on a humanoid alien who is stranded on Earth, the planet he was supposed to study. In his journey, he experiences many aspects of humanity, including religions, customs, languages, attire, practices and beliefs.
After the success of 3 Idiots (2009), Hirani and Joshi's began scripting their next project; finding similarities with the plot of Inception (2010), they scrapped the film. It was later rewritten with a different angle and tone. During production, the film was first titled Talli and later Ek Tha Talli before being changed to PK as the latter title was found too similar to Ek Tha Tiger (2012). 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.
