Sedin Dujone (Bengali: সেদিন দুজনে) is a 2008 Bengali film directed by debutant director Atanu Basu and released in 2008 featuring Amitava Bhattacharya and Kasturi. The film is almost directly from Priyadarshan directed Kyon Ki released in 2005, which was not an original storyline either. It was a variation on the famous Suchitra Sen-film Deep Jele Jai. This was later made into Hindi as Khamoshi, produced by Hemant Kumar and starring Waheeda Rehman. But like most of his peers, Bose does not credit his source.
