Complainant Sarvajan Jagruti Sanstha has alleged that not only does it violate moral ethics, but it also shows Varanasi in poor light.
The social organization filed the complaint at Bhelupur police station on Sunday.
"The film hurts religious sentiments and we cannot allow such a film to be released," a complainant told IANS.
The film is based on a novel - "Kashi Ka Assi" - written by acclaimed Hindi writer Kashinath Singh.
The film also stars Ravi Kishen and Sakshi Tanwar.
Sunny Deol plays the lead role of a Sanskrit teacher and an orthodox religious priest (Pundit) while Sakshi Tanwar plays his wife.
