When discussing Poonam Das Gupta, the film Vashyam is frequently at the center of the conversation. Released during a time when the Indian film industry was experimenting with bolder themes, Vashyam became a standout project for her. The "Vashyam scenes" are often cited by fans for their intense atmosphere and Poonam’s ability to command the screen.

The sun dips low over South Delhi, casting honey-gold shadows through her sheer curtains. On the center table, a copy of Architectural Digest sits beside a brass diya, its flame steady. Poonam isn’t posed; she is the composition. Silk kurta in dusty rose. Bangles that chime like tiny wind bells when she reaches for her evening chai—cardamom, no sugar, served in bone china that once belonged to her mother-in-law.

She gained a reputation for her roles in horror films such as Aakhri Cheekh , Papi Gudia , and Khooni Tantrik .
