As police officer Jahangir drives home, clutching a small glass bottle, his recent completion of a murder mystery assignment brings him no sense of triumph. Unbeknownst to SI Miraz, he is caught in a time loop, unsure of its destination. Shehzad, with his enigmatic persona, sets the stage, leading the audience seamlessly from a Bangladeshi web series' murder mystery to the realm of science fiction. I'm referring to the recent release of “Kaalpurush” on the OTT platform Chorki, a series quickly gaining acclaim for its adept fusion of murder mystery and sci-fi elements.

Apart from the “Monpura” actor, the series also features FS Nayeem and Tanzika Amin in significant roles.

Earlier, the first look of FS Nayeem in the "Kaalpurush" teaser surprised the audience, as he underwent a massive transformation, gaining 30 kgs for his role. 

Director Salzar Rahman used to direct music videos and ad-films. Sharing about the plot of “Kalpurush” he said, "I had visited a medicine shop in Old Dhaka a long time ago. The story of this series came to mind for various reasons from there. Then I wrote the series during the time of Covid-19 quarantine period.”
