India, Feb. 22 -- Actor Aamir Khan has revealed that neither he nor PK director Rajkumar Hirani were "totally happy" with their sci-fi satirical 2014 film. Speaking with Variety India, Aamir said that they had to change the second half of the film as "some of the themes were similar" to Akshay Kumar and Paresh Rawal's 2012 film Oh My God.

Aamir said the original script of the film was different. "In case of PK, which was a huge success, both Raju and I were not really fully happy with the film. Because originally, he had written a different script. And the second half was slightly different from what we had made. But there was another film that came out just before us called OMG - Oh My God and the themes were kind of similar," he said....
