Speaking on portraying the filmmaking icon on the big screens, Chanchal Chowdhury said, "One needs courage and qualifications to play Mrinal Sen on big-screens. My courage and qualifications will be tested in this film."

"It still feels unreal to play Mrinal Sen but actors do have to take such roles considering their dreams," the popular Bangladeshi actor added.

A few days ago, Bollywood legend Amitabh Bachchan sent "good wishes" to the film, which will go on floors in Kolkata on Jan 15.

Bachchan tweeted, "All good wishes .."

Mukherji's Padatik shares the title with Sen's iconic 1974 film, which is considered as a part of his Calcutta Trilogy.
