The much-awaited trailer of O.M: Operation Mole has finally been released, offering audiences a gripping glimpse into a world of red sandalwood smuggling, undercover operations, crime and intense confrontations. Headlined by Dhanush, the upcoming action thriller also features Malayalam superstar Mammootty and Sai Pallavi in pivotal roles. The nearly three-minute trailer promises an intense cinematic experience, with all three actors making a strong impression.
Directed by Rajkumar Periasamy, known for his work on Amaran, the film takes audiences into the forests of Andhra Pradesh, where an illegal red sandalwood smuggling network becomes the centre of a major police investigation.
Dhanush appears in a completely intense avatar as an undercover officer who infiltrates the criminal syndicate. Sai Pallavi plays Nithya Reddy, a police officer leading Operation Mole, while Mammootty’s mysterious and powerful character adds another layer of intrigue to the story.
The trailer was unveiled on November 13, ahead of the film’s scheduled theatrical release on November 20, 2026. The project is being presented as the first instalment of a planned two-part franchise.
O.M Trailer: Dhanush Goes Undercover Against Red Sandalwood Mafia
The trailer introduces Dhanush as an undercover officer working with Tamil Nadu’s organised crime intelligence unit. His character enters the red sandalwood smuggling network by disguising himself as a woodcutter.
As the story progresses, he becomes deeply involved with the syndicate, attempting to identify the people controlling the illegal trade.
The forest setting, dramatic confrontations and action sequences create an atmosphere of suspense throughout the promotional video.
One particularly interesting aspect is the ambiguity surrounding Dhanush’s character. Certain scenes make it appear as though he is fighting against the police, leaving viewers wondering how far his undercover identity extends.
The narrative appears to revolve around a joint operation involving police forces from Andhra Pradesh and Tamil Nadu to dismantle the powerful smuggling network.
Dhanush’s transformation and intense screen presence are among the biggest highlights of the trailer.
Mammootty Steals the Show With His Powerful Character
One of the biggest attractions of O.M is Mammootty’s appearance.
The veteran actor plays a grey-shaded character named Siya, who appears to have significant control over the red sandalwood trade. His character is presented as a powerful figure operating behind the scenes.
The trailer offers glimpses of Mammootty’s commanding screen presence, mysterious expressions and confrontational moments.
His character appears to be connected to the criminal network at a much higher level, creating an interesting conflict with the police operation led by Sai Pallavi.
The collaboration between Dhanush and Mammootty is another major talking point. Their first on-screen collaboration brings together two celebrated performers from different film industries.
Although their characters’ complete relationship remains under wraps, the trailer hints at an important confrontation between them.
Mammootty’s presence gives the film another major attraction, particularly for audiences looking forward to seeing him in a different kind of role.
Sai Pallavi Leads Operation Mole as Nithya Reddy
Sai Pallavi is another major highlight of the O.M trailer.
The actress portrays Nithya Reddy, an officer leading Operation Mole, the mission designed to expose and dismantle the red sandalwood smuggling network.
Unlike her familiar romantic and emotional roles, Sai Pallavi appears in a commanding police avatar.
Her character is shown handling the investigation and coordinating the operation against the criminal network.
The trailer gives her several important moments, showcasing her authority, determination and involvement in the central conflict.
Her pairing with Dhanush is also attracting attention. The two actors previously worked together in Maari 2, and their reunion in this action thriller has generated curiosity among fans.
Sai Pallavi’s character appears to be central to the narrative rather than simply serving as a supporting presence.
Sreeleela, Naseeruddin Shah and Indrans Join the Cast
Apart from the three leading performers, the film also features Sreeleela, Naseeruddin Shah and Indrans in important roles.
Sreeleela reportedly plays Dhanush’s wife, adding an emotional dimension to the otherwise crime-driven narrative. Naseeruddin Shah’s character details have largely been kept under wraps, increasing curiosity around his appearance.
Indrans also plays an important part in the film.
The ensemble cast brings together actors from different film industries, making O.M an interesting pan-Indian cinematic project.
Rajkumar Periasamy Returns After Amaran
O.M is written and directed by Rajkumar Periasamy, who previously directed the successful Tamil film Amaran, starring Sivakarthikeyan and Sai Pallavi.
Following the response to Amaran, expectations are high for his next directorial venture.
With O.M, the filmmaker explores a crime-action narrative inspired partly by real-life incidents.
The story is set against the backdrop of the Seshachalam forest region in Andhra Pradesh, known for its red sandalwood resources.
The director has reportedly drawn inspiration from an incident dating back to 2014 while developing the film’s emotional foundation.
The narrative combines an undercover investigation with questions surrounding illegal trade, power and the exploitation of forest resources.
Sai Abhyankkar’s Music Adds to the Intensity
The film’s music and background score have been composed by Sai Abhyankkar.
The trailer features dramatic sound design and energetic musical arrangements that complement its action-oriented presentation.
Ezhil Arasu K has handled cinematography, while R. Kalaivanan is responsible for editing.
The action sequences have been choreographed by Yannick Ben and Kecha Khamphakdee.
The forest locations, atmospheric visuals and large-scale presentation appear to be important elements of the film’s cinematic world.
O.M Release Date: When Will Dhanush’s Film Hit Theatres?
November 20, 2026
O.M: Operation Mole is scheduled for a worldwide theatrical release on November 20, 2026.

With the trailer now released, the promotional campaign has entered its final phase ahead of the theatrical debut.
O.M Trailer Twitter Review: What Are Viewers Saying?
The trailer has generated considerable discussion on social media.
Viewers have particularly highlighted the combination of Dhanush, Mammootty and Sai Pallavi.
Mammootty’s powerful appearance, Dhanush’s intense transformation and Sai Pallavi’s police avatar have emerged as major talking points.
Several viewers have also appreciated the film’s visual presentation and action sequences.
However, Sai Abhyankkar’s background score has received mixed reactions, with some viewers expressing different opinions about the music.
Overall, the trailer has increased curiosity around the film, especially because of its unusual combination of actors and its red sandalwood smuggling backdrop.
