Mukherji initially wanted Prosenjit Chatterjee for the role of Ron, but scheduling conflicts led to Parambrata Chatterjee being cast. Rukmini Maitra, who had previously played glamorous roles, underwent intense workshopping to play the more vulnerable, conflicted Meghna. Anirban Bhattacharya, known for his intense method acting, reportedly isolated himself for two weeks to channel Arjun’s "creative rage."

3 on a Bed is a Bengali-language film that blends contemporary family drama with light romantic comedy. Released in 2019, the film follows the intersecting lives of three housemates who must confront past relationships, evolving friendships, and the practicalities of sharing a home in modern Kolkata.

Despite the lurid title, director Sudipta Roy shoots the relationship with a detached, arthouse lens. Think Jules and Jim meets Kolkata coffee houses. The "bed" scene is less about sex and more about intimacy—pillow fights, sharing cigarettes, and philosophical debates about possession.
