He still remains a source of inspiration for many upcoming Bengali Film Directors. Mrinal Sen has made films in Bengali, Oriya, Telugu, and Hindi. Mrinal Sen, in 1955, directed first feature film named, Raatbhor. The cinema did not do that well in the box office and failed miserably. His next film, Neel Akasher Neechey (Under the Blue Sky), got him local fame and popularity, but his third film, Baishey Shravan (the day when Rabindranath Tagore died) gave him international exposure and people loved and appreciated his work for the first time.
