Rajkumar Hirani is known for making some of the most unique Bollywood films, such as ‘Munna Bhai MBBS’, ‘Lage Raho Munna Bhai’, and ‘3 Idiots’. In a recent interview, Rajkumar shared that he faced some difficulties in the making of the Aamir Khan-starrer ‘PK’, as the movie eventually started showing an uncanny resemblance to Christopher Nolan’s ‘Inception’.
