This was Challenger a.k.a. A.S.M. Tofazzal Hossain's first on-screen appearance in an acting role. His first on screen appearance however, was in a scene in Dui Duari (2000) in a non speaking role. He can be seen offering food to Mahfuz Ahmed's character, Shafik, in a scene when he is sick and goes back to his village by train.
The theme song "Hablonger Bazare", sang by Shubir Nandi, was later added to "Humayun Ahmeder Shorone" album after his death in 2012.
This is a notable role for Dr. Ejazul Islam. Humayun Ahmed briefed the character to him with his own words to define his performance. Normally he wouldn't say it dialogue by dialogue, but this was an extraordinary exception.
