"It is such an honest film, a film with so much of heart and truth and that's the reason it is such a big hit. I think only Raju, Vidhu and Aamir can make such films," the actor said here on Thursday at the film's screening, which was organised especially for him.
Directed by Hirani and co-produced by Hirani and Vidhu Vinod Chopra, 'PK' features Aamir as an alien. The film takes a hard-hitting swipe on organised religion, god and godmen.
Sanjay also has a role to play in 'PK', which hit screens on Dec 19, and crossed the Rs 100-crore mark within four days of its release. It is still going strong at the box office.
