At the time of filming Rituparna Sen, who in the movie performs an unsimulated fellatio to Anubrata Basu, was in a long term love relationship with movie director Qaushiq Mukherjee. Asked if the actress was comfortable with that, Rii says, "I didn't have any problems at all. I have been a professional actress for 10 years now. It doesn't bother me if the camera is off or on." But still, any explicit shot requires preparation. Speaking of the workshops they did to prepare themselves for the sex scenes in Gandu, Rii says: "They were physical workshops that helped us shed our inhibitions and become real. If someone were to touch my boobs, it's natural that I'd be aroused. But it is the aftermath that is important. How do you feel after such a shoot? I wasn't shattered or anything after I shot Gandu. I was shooting lovemaking scenes with my co-actor that were being shot by my boyfriend. Now, how weird is that?"
Due to the extreme and graphic sexuality in the film, it was banned in India for seven years, before being finally released unofficially on the internet in 2017.
