Resuming work soon after performing the last rites of his father, Saif Ali Khan broke down on the sets of ‘Agent Vinod’. Apparently, the actor had to return to Mumbai from Patuadi to complete shoot of the already delayed ‘Agent Vinod’, but the terrible grief took its toll on Saif, leaving him teary eyed. Death of Mansur Ali Khan Pataudi gave way to Saif’s irreparable loss in a very emotional way. Reportedly, Saif wanted to spend some more time with his family, but he had no option but to return immediately because of his film. A source from the sets revealed, “In between a shot Saif lost his composure and broke down. He looked teary-eyed and dejected. He even asked director Sriram Raghavan for a small break, and went straight to his vanity van. He returned after some time though and gave the shot. You can easily make out that he is still struggling with his emotions, which is quite understandable considering his father recently passed away.” The actor, who was said to be very close to his father, is yet to come to terms with the personal loss.
