After a long wait, the makers of OM have finally released the trailer of the film, officially titled OM: Chapter 1, Udhiram: The Blood Wood. Starring Dhanush, Sai Pallavi and Mammootty, the film revolves around the illegal red sandalwood trade, a secret CBI operation and a criminal network operating between two temple towns.
The trailer was initially scheduled to release at 7 PM on November 13. However, the launch event was delayed by several hours, and the video was finally released close to midnight. It soon started trending on social media, with many early viewers sharing positive reactions.
Sai Pallavi plays a CBI officer
The trailer opens with the words “Some of these things actually happened” appearing on screen as Suprabhatam, a morning prayer commonly heard in South Indian Hindu households, plays in the background.
The story introduces Operation Mole, a secret mission led by CBI officer Nithya Reddy, played by Sai Pallavi. Seen in a police uniform, she leads the investigation into the illegal red sandalwood trade. This role offers a different look at the actress compared to her portrayal of Sita in Ramayana.
The film is set between two temple towns, where red sandalwood smuggling has become a major illegal business. Some visuals also suggest inspiration from real incidents involving woodcutters in the Tiruvannamalai forest region.
Dhanush’s identity and Mammootty’s role remain intriguing
Dhanush plays D-402, a member of the D team in the organised crime intelligence unit. He is also seen as a woodcutter who gets involved in the smuggling network. However, the trailer leaves his actual position unclear. He could be working undercover, or he may have a deeper connection with the criminal syndicate.
Mammootty plays Siya, also known as Burma Karthikeyan or Burma Karthik. His character appears to have considerable influence over the smuggling business, with some scenes suggesting political connections. The film also marks his return to Tamil cinema after nearly seven years.
Sreeleela plays Dhanush’s wife, while Naseeruddin Shah makes a brief appearance in the trailer. His role has not been revealed yet.
OM: Chapter 1 release date
Sai Abhyankkar has composed the background score, while Yannick Ben and Kecha Khamphakdee have choreographed the action sequences.
Written and directed by Amaran fame Rajkumar Periasamy, the film is produced by Wunderbar Films and RTake Studios. Planned as the first part of a duology, OM: Chapter 1 will arrive in cinemas on November 20. The trailer has been released just six days before its theatrical opening.
