MUMBAI: Siddhant Cinevision has bought the rights of Sunil Gangopadhyay’s controversial novel Ranu O Bhanu based on Nobel Laureate Rabindranath Tagore’s life.

The novel is one of the most controversial of recent times as it is said that Ranu O Ranu explores Tagore’s romantic relationship with his sister-in-law.

Finding it rather interesting, producer Manish Goswami has decided to make a film based on it. The producer wants to keep everything rather hush-hush at the moment. But he has made his intention clear of casting Amitabh Bachchan in Tagore’s role.

Selection of cast and crew is in progress.
