OM Trailer Arrives Today: Dhanush, Mammootty and Sai Pallavi’s Actioner Drops Its Trailer Ahead of November 20 Release
The trailer for OM – Chapter 1: Udhiram – The Blood Wood arrives today, Friday, November 13. Dhanush’s Wunderbar Films shared a new announcement poster on social media yesterday, confirming the trailer launch exactly a week before the film’s theatrical release on November 20, 2026. The poster shows Dhanush in a blood-stained outfit holding a camera, against a red and dark-blue backdrop, with Mammootty and Sai Pallavi partly visible behind him — a first proper look at the three stars together.
The film is one of the most anticipated Tamil releases of the month, and the casting is the reason. Dhanush headlines alongside Mammootty in a pan-Indian action thriller directed by Rajkumar Periasamy, who previously directed Sai Pallavi in Amaran. Pallavi plays IPS officer Nithya Reddy, leading an operation against the illegal red sandalwood trade — the “blood wood” of the title — with Sreeleela, Naseeruddin Shah and Indrans in support. The film was originally scheduled for October 16 before being postponed to November 20, and it is planned as the first instalment of a two-part franchise. Wunderbar Films is producing with RTake Studios, and Sai Abhyankkar has composed the music.
The build-up has been deliberately paced. On October 26 the makers released a character glimpse titled “OM Special Duty”, introducing Pallavi’s Nithya Reddy — a determined officer following in her father’s footsteps — and the Tamil version crossed 2.2 lakh views within about an hour of release. Lyrical videos and Mammootty’s entry glimpse have followed since, but the full trailer has been held back until today, a week out from release, which is a short runway by the standards of a film of this scale.
Here is the Filmverse take: holding the trailer until seven days before release is a confident move, and it only works if the film has something to show. The Dhanush–Mammootty pairing is the draw — two actors from different industries and different generations who have never shared a frame like this — and Periasamy’s Amaran proved he can build a mainstream action film around a real operation without losing the human story. The red sandalwood setting invites comparison with Pushpa, but OM’s pitch is different: a police procedural built around an officer rather than the smuggler. If today’s trailer lands that distinction clearly, the film goes into its final week with genuine momentum; if it looks like familiar territory, the short runway leaves little time to recover.
