Honestly, walking into a prison drama usually feels like a predictable trap. You expect the clichéd "hardened criminal with a heart of gold" or the "super-cop" who kicks down doors. But when the black warrant series cast was first announced, people were kinda confused. Who is this new kid, Zahan Kapoor? Why is Rahul Bhat playing a slimy DSP? And how on earth do you make a show about Tihar Jail without it turning into a cheap Singham knockoff?
The reality of Black Warrant, which hit Netflix in early 2025, is much weirder and darker than the trailers let on. It isn't just a show about bars and beatings; it’s a workplace drama where the office happens to be Asia’s most notorious prison. The series, steered by Vikramaditya Motwane and Satyanshu Singh, pulls its soul directly from the 2019 memoir by Sunil Gupta and Sunetra Choudhury.
The Rookie in the Lion's Den: Zahan Kapoor as Sunil Gupta
The biggest gamble for this show was casting Zahan Kapoor. Yeah, he’s a Kapoor—the grandson of the legendary Shashi Kapoor—but he doesn't have that "hero" energy we’re used to. And that’s exactly why it works.
Zahan plays Sunil Gupta, a vegetarian, soft-spoken rookie who walks into Tihar in 1981 looking like he’s about to faint. He’s basically the human version of a deer in headlights. Most actors would have tried to make Gupta look "tough" by the third episode. Zahan doesn't. He stays wispy and tentative, capturing that specific anxiety of a man who realizes his job is viewed by society as "menial" or even "shameful."
It’s a breakout performance because he nails the accent and the subtle evolution from a naive kid to a man who understands that in Tihar, the "black warrant" isn't just a piece of paper—it’s a heavy, crushing reality.
The Supporting Trio: Dahiya, Mangat, and the Slimy DSP
If Sunil is the heart of the show, the other three jailers are the muscle and the bile. This is where the black warrant series cast really finds its rhythm.

- Rahul Bhat as DSP Rajesh Tomar: Rahul Bhat is basically the king of playing "grey" characters now. As Tomar, he’s opportunistic and cynical. He’s the boss who treats the jail like a personal fiefdom, yet the show gives him these tiny, broken moments that stop him from being a cartoon villain.
- Anurag Thakur as Vipin Dahiya: Honestly, Dahiya is the sleeper hit of the show. He’s a hot-headed Haryanvi who seems like he’s just there for the violence, but Anurag Thakur gives him this "childlike innocence" (as actress Tillotama Shome reportedly put it) that makes you root for him despite the corruption.
- Paramvir Singh Cheema as Shivraj Singh Mangat: Mangat provides the emotional weight. He’s a Sikh officer struggling with the rising insurgency in Punjab and his own brother’s involvement in it. Cheema plays him with a quiet, haunted intensity that feels very "Tabbar-esque."
The Most Controversial Casting: Sidhant Gupta as Charles Sobhraj
Let’s talk about the elephant in the room. Or rather, the "Bikini Killer" in the cell.
Sidhant Gupta playing Charles Sobhraj was a massive risk. We’ve seen Sobhraj portrayed many times, but Sidhant plays him as a charming, manipulative enigma who treats the prison like a high-end hotel. He doesn't go for the "scary murderer" vibe. Instead, he’s the guy who talks his way into getting better food and influencing every jailer he meets.
The chemistry—or rather, the creepy psychological tension—between Sidhant’s Sobhraj and Zahan’s Sunil is one of the best things about the show. It’s a cat-and-mouse game where the mouse (Sunil) doesn't even realize he's being played for the first few episodes.
Why the Ensemble Works Better Than a Solo Lead
Usually, Indian series lean heavily on one "superstar." Black Warrant doesn't do that. It feels more like The Wire or a gritty retro police procedural.
The cast is stacked with veterans who ground the world. You’ve got Rajendra Gupta playing Saini Saab, a mentor figure who provides the moral compass. Then there's Rajshri Deshpande as Pratibha Sen, the journalist trying to get inside the heads of death-row inmates.
Even the smaller roles, like the actors playing the infamous Ranga and Billa (Puran Gabbi plays Ranga), are cast with a focus on realism over "acting." When the black warrant is finally issued for their execution in episode two, you don't feel like you’re watching a movie. You feel the cold, mechanical horror of the state preparing to kill someone.
The "Real" vs. "Fictional" Cast Dynamics
One thing most viewers get wrong is assuming every character is a real person. In a 2025 interview, Vikramaditya Motwane clarified that while Sunil Gupta is real, the other jailers (like Dahiya and Mangat) are often composites or fictionalized versions of people mentioned in the book.
This allowed the writers to explore themes like the 1984 anti-Sikh riots and the JNU student protests of the 80s through characters who have a personal stake in those events. It’s smart writing. It makes the prison feel connected to the outside world, rather than an isolated island.
Key Takeaways for Fans of the Series
If you're looking to dive deeper into the world of Black Warrant, here’s what you should actually pay attention to:
- Watch the background: The "Tyagi" and "Haddi" gangs aren't just there for filler; their shifting alliances reflect the actual power struggles of 80s Tihar.
- The Soundtrack: The retro score isn't just for "vibes." It highlights the disconnect between the "cool" Bollywood cop movies Sunil grew up on and the depressing reality of his desk job.
- The "Snake" Motif: Keep an eye on the recurring mention of snakes (snaap). It’s a metaphor for the corruption that slithers through the jail, and it pays off in a big way by the season finale.
Actionable Insights for Viewers
- Read the Source Material: If you’re fascinated by the cast's performances, pick up the book Black Warrant: Confessions of a Tihar Jailer. It provides the "unfiltered" versions of the events that were too dark even for Netflix.
- Look for the Cameos: There are several "blink-and-miss-it" appearances of real-life figures from Indian history during the JNU arrest sequences.
- Follow the Newcomers: Actors like Zahan Kapoor and Anurag Thakur are clearly going to be the next big things in the "Indie-OTT" space. They chose a gritty, non-commercial debut for a reason.
The black warrant series cast succeeded because they didn't try to be heroes. They played people who were just trying to survive a shift at the world’s most dangerous office. It's grim, it’s uncomfortable, and honestly, it’s some of the best Indian television we’ve seen in years.
To truly understand the show's impact, compare the final execution scene with the early, almost comedic scenes of Sunil's orientation. The shift in tone is entirely dependent on the actors' ability to show the "hardening" of their souls over seven episodes. That’s not just good casting; that’s great storytelling.
