One of the main reasons that the creators set up the plot in Delhi was that it's the apex of the Indian political scene and where the power centers lie. Sudip said that 70% percent of Paatal Lok had been shot at actual locations in Delhi, Gurgaon, and Rohtak.
The makers of the show give us a glimpse into what their idea behind the creation of the show was as they said that they wanted to explore different cultures, perspectives, and tales from various regions, as well as the divides.
Their point is to bring to the audience what they possibly don't know about, or at least in a manner, what they haven't seen. The show has been set up in regions of Delhi, UP & Punjab.
In a previous interview, Sudip mentioned that he has spent a lot of his time in Delhi and Punjab, Bundelkhand and UP, for the research he did for his previous works.
The creators of the show have done an extensive research to bring to the audience the closest picture to reality. Sudip states that the objective was to keep it as authentic as possible. The audience waits to see what the show has in store for them. So mark your calendar everyone!
