The entire shooting for the film was done in Humayun Ahmed's own estate, Nuhash Polli in Gazipur, Bangladesh.
Actor Challenger and actress Diti are on-screen couple. Both of them died of brain cancer: Challenger in 2010, Diti in 2016
Actress Shawon (wife of Humayun Ahmed) was pregnant during the filming. Humayun Ahmed cast her as a singer instead.
Humayun Ahmed was a die-hard fan of Rabindranath Tagore. That's why he added a Rabindra sangit sang by Shawon so that the movie can show Humayun Ahmed and Tagore's name in a same frame under the music credits/lyricists.
Togor (youngest son, the nerd) is a bit sane version of the famous Anis from Aj Robibar.
