The trailer of OM: Chapter 1 – Udhiram: The Blood Wood is out, bringing Dhanush, Mammootty and Sai Pallavi together in an action thriller centred on the illegal red sandalwood trade. Directed by Rajkumar Periasamy, the film promises a tense police operation, undercover action and a clash between powerful characters. It is scheduled to arrive in cinemas worldwide on November 20, 2026.
The nearly three-minute trailer offers a closer look at the film’s central conflict, set in the Seshachalam forest region of Andhra Pradesh. Dhanush plays an officer from Tamil Nadu’s Special Task Force who enters a red sandalwood smuggling network undercover. Disguised as a woodcutter, he attempts to gain the syndicate’s trust and identify the people controlling the illegal business.
The trailer also introduces an intriguing layer of uncertainty around his mission. Some sequences show Dhanush appearing to fight against the police, raising questions about how far his undercover operation goes and whether his cover remains intact.
Sai Pallavi Leads Operation Mole as IPS Officer Nithya Reddy
Sai Pallavi takes on the role of IPS officer Nithya Reddy, who heads Andhra Pradesh’s Exclusive Special Task Force. Her character leads Operation Mole, a mission aimed at dismantling the red sandalwood smuggling network.
The trailer presents her as a determined officer at the centre of the investigation. Her role places her on the other side of Dhanush’s undercover assignment, creating another point of tension within the larger operation.
Mammootty, meanwhile, appears as Siya, a powerful and mysterious figure connected to the illegal trade. The trailer suggests that his character operates behind the scenes and may have considerable influence over the smuggling network. His face-offs and screen presence add another dimension to the film’s central conflict.
Sreeleela also features in the trailer, although the makers have kept several details about her character under wraps. The film additionally features Naseeruddin Shah and Indrans.
Sai Abhyankkar’s Music Adds to the Action
The film’s visuals and action sequences are accompanied by music from Sai Abhyankkar. The background score builds momentum through the trailer’s quieter moments and high-energy confrontations.
The trailer follows the release of three songs from the soundtrack: ‘Alaakaa Loova’, ‘Veezha Veera’ and ‘Senjudare’. The tracks have been part of the film’s promotional campaign ahead of its theatrical release.
Speaking about the trailer launch, producer Shraddha Agrawal of RTake Studios said it gives audiences a sense of the world created by director Rajkumar Periasamy. She also expressed hope that the trailer would build on the response to the film’s music and bring more viewers into its cinematic world.
