West Bengal is one such place that provides a unique combination of history and art. Bollywood box office smashes have all chosen West Bengal for their masterpieces over the years. This chapter is a new approach to assessing the effects of the detective series “Durgeshgorer Guptodhan,” which reveals unknown sites once popular for castles, temples, or mausoleums in West Bengal. In doing so, this chapter focuses on how unknown and lesser-known places are coming to light, and tourists and excursionists are getting increasingly interested in these sites and historical and cultural edifices. Further, this chapter unveils a new trend in how film series or documentaries with sequences can be planned beforehand for destination promotion and the inclusion of lesser-known destinations as well. Coincidentally, this new trend is found useful for not only bringing unknown or lesser-known destinations to light but also to extend economic and entrepreneurial support to many local people.
