Indian cinema fans have a new reason to get excited. The much-awaited trailer of OM: Chapter One has finally arrived, bringing together three popular performers: Dhanush, Mammootty and Sai Pallavi. Directed by Rajkumar Periasamy, the upcoming action drama promises a gripping combination of crime, undercover operations, political power and intense action.
The trailer has already attracted attention for its powerful character introductions, dramatic visuals and intriguing storyline. With elements that remind viewers of Dhurandhar and Pushpa, OM appears ready to deliver a different kind of action-packed theatrical experience.
But what makes this trailer so interesting? Let's explore its biggest highlights, cast, storyline and release details.
What Is OM: Chapter One About?
OM: Chapter One is an upcoming action thriller directed by Rajkumar Periasamy, known for films such as Rangoon and Amaran.
The story revolves around organised crime, red sandalwood smuggling and a police operation designed to expose a powerful criminal network. Set between two temple towns, the film brings together law enforcement agencies, undercover missions and dangerous criminal connections.
The trailer introduces Operation Mole, also known as OM, which becomes central to the investigation. As the mission progresses, the characters face difficult situations where loyalty, identity and personal responsibilities become increasingly complicated.
The storyline looks ambitious, with a mix of action, crime and emotional drama.
Dhanush's Powerful Role Grabs Attention
Dhanush is one of the biggest attractions of the OM trailer. He plays a member of the Organised Crime Intelligence Unit (OCIU), operating under the identity D-402.
His character becomes involved in an undercover mission to investigate the red sandalwood smuggling network. The trailer offers glimpses of intense action, dangerous situations and a complicated double life.
One interesting detail is his character's family situation. His wife, played by Sreeleela, and their son cannot openly be associated with his secret professional identity.
This adds an emotional dimension to the otherwise action-heavy storyline. Dhanush's intense appearance and character transformation are among the trailer's major talking points.
Mammootty Appears in a Powerful Negative Role
Mammootty brings another major attraction to the film. He plays Red Hills Karthikeyan, also known as Burma Karthikeyan, a powerful figure connected to the red sandalwood smuggling network.
His character appears to combine criminal influence with political power, making him an important part of the film's central conflict.
The trailer gives viewers a glimpse of his commanding screen presence and dangerous personality. His face-off with Dhanush is particularly interesting because both actors bring very different acting styles to the screen.
For fans, seeing these two talented performers together is one of the biggest reasons to look forward to the film.
Sai Pallavi Leads Operation Mole
Sai Pallavi also gets an important role in OM. She plays ASP Nithya Reddy, who leads Operation Mole to investigate the organised smuggling network.
Her character appears determined, focused and deeply involved in the mission. The trailer offers glimpses of her investigating the criminal operation and dealing with the challenges surrounding it.
Rather than simply serving as a supporting presence, Sai Pallavi appears to have a significant role in driving the story forward.
Her combination with Dhanush and Mammootty adds further interest to the film's cast.
Why Is Everyone Comparing OM With Dhurandhar and Pushpa?
One of the most discussed aspects of the OM trailer is its resemblance to two popular action films: Dhurandhar and Pushpa.
There are a few reasons behind these comparisons.
1. The Red Sandalwood Crime Network
The film's focus on red sandalwood smuggling and powerful criminal groups naturally reminds viewers of the world presented in Pushpa.
2. Undercover Investigation
Dhanush's involvement in an undercover operation creates similarities with the espionage and infiltration elements associated with Dhurandhar.
3. Political Influence and Organised Crime
The trailer also highlights the connection between criminal networks and political power, creating a tense atmosphere.
However, these similarities do not necessarily mean OM follows the same storyline. Its final identity will depend on the screenplay, character development and direction.
5 Biggest Highlights of the OM Trailer
Here are five elements that make the trailer worth watching.
Dhanush and Mammootty's First Collaboration
The combination of two established performers is one of the biggest attractions. Their contrasting characters could create some memorable confrontations.
Sai Pallavi's Police Officer Character
She plays CBI officer Nithya Reddy, who investigates the red sandalwood smuggling network. Her character adds an important investigative angle to the film.
An Interesting Crime Story
Red sandalwood smuggling, organised crime and undercover operations provide an intriguing foundation for the film.
Rajkumar Periasamy's Direction
After Amaran, expectations are high for Rajkumar Periasamy's next project. OM gives him an opportunity to explore a large-scale crime action drama.
A Promising Supporting Cast
Apart from the lead actors, the film also features Sreeleela, Naseeruddin Shah, Indrans, Sanjay Swaroop and Renu Desai in important roles.
Music, Background Score and Cinematic Experience
Music is another important part of an action film, especially when the story involves large-scale confrontations and dramatic character introductions.
Sai Abhyankkar has composed the music and background score for OM. The trailer uses dramatic sound design and action sequences to establish its intense atmosphere.
While many viewers have appreciated the overall presentation, reactions to the background score have been mixed. This makes the film's complete soundtrack another element worth watching after its theatrical release.

OM has several elements that could attract moviegoers. A strong lead cast, a crime-based storyline, undercover missions and a director with a successful previous film have already created curiosity.
The biggest challenge will be delivering a screenplay that feels fresh despite comparisons with other popular action films.
Dhanush's character, Mammootty's powerful antagonist and Sai Pallavi's leadership in Operation Mole could become the film's strongest attractions.
