The first full trailer of OM: Chapter 1, Udhiram: The Blood Wood is finally here, and it wastes no time announcing scale. Dhanush charges into full mass mode, Mammootty brings a composed but imposing presence, and Sai Pallavi flashes fierce intensity as IPS officer Nithya Reddy in a promo that leans hard into action, tension and big-screen spectacle.
Directed by Rajkumar Periasamy, OM: Chapter 1, Udhiram: The Blood Wood is now locked for a worldwide theatrical release on 20 November 2026. The trailer arrives as the film sharpens its pitch as a star-led action drama, with sweeping visuals, combat-heavy staging and a mood that suggests a story driven by power, conflict and survival.
Trailer Pushes Om Into Event Film Territory
What stands out immediately is the balance of its star power. Dhanush is presented in a full-fledged commercial avatar, while Mammootty’s controlled screen presence gives the trailer a steady counterweight. Sai Pallavi’s glimpse as IPS officer Nithya Reddy lands with force, and Sreeleela adds a lighter spark to the otherwise charged footage.
Sai Abhyankkar’s background score does a lot of the heavy lifting here, moving between restraint and eruption as the visuals build toward larger confrontations. The trailer follows the release of three songs from the film’s soundtrack, Alaakaa Loova, Veezha Veera and Senjudare, helping sustain momentum ahead of the film’s November opening.
Speaking about the trailer, Shraddha Agrawal, producer, RTake Studios, said, “With the trailer, audiences finally get a sense of the world Rajkumar Sir has created and what OM will feel like on the big screen. It’s been wonderful to see the music connect with listeners around the world, and we hope the trailer builds on that excitement and brings even more people into the world of OM.”
Cast, Crew And Film Details
OM: Chapter 1, Udhiram: The Blood Wood is directed by Rajkumar Periasamy and stars Dhanush, Mammootty, Sai Pallavi, Sreeleela, Naseeruddin Shah and Indrans. It is produced by Shraddha Agrawal, Dhanush and Azmat Jagmag under RTake Studios and Wunderbar Films. The film is positioned as an action drama mounted on a large canvas, with the trailer hinting at a world shaped by violence, authority and high-stakes confrontations.
Its two-minute-plus promo keeps plot specifics guarded, but the emphasis is clear. This is a theatrical play, driven by scale, star presence and an escalating conflict that the makers want audiences to experience in cinemas.
Dhanush’s Recent And Upcoming Work
For Dhanush, OM: Chapter 1, Udhiram: The Blood Wood adds to a phase where he has continued to move between star-driven commercial cinema and filmmaker-led projects. His recent releases include Captain Miller in 2024 and Nilavuku En Mel Ennadi Kobam in 2025, while Tere Ishk Mein remains one of his notable confirmed upcoming titles beyond OM.
That makes OM an especially interesting pivot. It places him in a full-scale action setup opposite Mammootty, under a director known for staging emotion and tension with precision. With the trailer now out and the release date fixed for 20 November 2026, the film has entered its most visible stretch yet.
