"Baishali Srabon" seems to be a misspelling or variation of "Baishe Srabon," which translates to "Golden Autumn" in English. Without more context, I'll assume you're referring to a Bengali film titled "Baishe Srabon."
A: No, Baishe Srabon is an original screenplay by Srijit Mukherji. It has a cult following for its unique blend of poetry and crime.
