The film will be produced by Virendra K. Arora and Arjun N. Kapoor.
"'Amar Hai' is special to us in many ways. One, it is that iconic project which is sure to mark the much awaited Kamal Haasan working for Hindi cinema. Two, the film will see Kamal Haasan wearing multiple hats, that of an actor and a director on a story penned by him.
"And three, from the outset of scripting this film since the past six years, Kamal Haasan has had Saif Ali Khan in mind for the lead role and the actor has been clued in about his involvement on the mega project," the makers said in a statement.
The story travels from Mumbai to North India and traverses some picturesque international cities as the plot progresses. The producers, along with the film's mastermind Kamal, are exploring shooting locations in Mumbai, Delhi, London, Dubai, Jordan and parts of the US.
Talking about his role, Kamal said: "My character though not that of a conventional antagonist would present a point of view that is far from ordinary."
Kamal is currently shooting for Tamil thriller "Thoongaavanam", while awaiting the release of another thriller "Papanasam".
