Director Prem Soni, who is making a biopic on the legendary musician Bhupen Hazarika, says the film is complex, complicated and fantastic.

The film chronicles the love story of late Hazarika and his companion for 40 years, Kalpana Lajmi. Names of actors like Ajay Devgn, Saif Ali Khan and Ranveer Singh have cropped up for the lead but Prem has rubbished such rumours.
