According to a unit member from Bangkok Blues, "Irrfan has been very insecure about Deepal. Every day of shooting was a nightmare because when he immediately become conscious of the fact that Shaw's role was stronger than his. He threatened to disrupt shooting until they made his role the meatier one. Our poor director Navneet Baj Saini had to change the scenes. We were in Bangkok, after all, and could not afford delays."
Deepal is the protagonist in Bangkok Blues and this apparently didn't go down well with Irrfan. The source adds, "Khan felt the film had become too woman-centric. As the bigger star, he felt her deserved better coverage.
After shooting ended, he also refused to dub for the film. Only after producer Irrfan Kamal complained to the IMPPA (Indian Motion Pictures Producers' Association) and the actor was issued a warning, did Khan finally complete dubbing."
Producer Kamal says, "All I can say is that Irrfan is the film's main lead along with Deepal and they both have given brilliant performances. I have heard about their cold war continuing even after shooting ended but would not like to comment on their personal matter."
What about his refusal to dub? Offers Kamal, "We had paid Irrfan but he was unable to give us dates. As per IMPPA law, we had to inform them. They, in turn, got us the dubbing dates from Irrfan. He has completed his parts and the film will release soon."
Irrfan Khan remained unavailable for comment.
