Sanjay Dutt plays the role of Bhairon Singh, who is Aamir Khan's loyal friend in Rajkumar Hirani's "PK." He is also a band member. Dutt had to dress up as a Rajasthani villager for this part, and he slipped into the role quite easily.
Dutt had to complete one day of shooting for "PK" when he was sentenced to jail, and he shot his last scenes just two days before he went to jail.
Dutt is very close to Vidhu Vinod Chopra and Rajkumar Hirani as he has done the hugely successful "Munnabhai MBBS" and "Lage Raho Munnaibhai" with the filmmakers, and last day of shoot was very emotional for everybody.
