Wunderbar Films has officially announced the new release date of OM Chapter One, bringing together two major stars from Indian cinema, Dhanush and Mammootty, for what promises to be an intense action spectacle. Directed by Rajkumar Periasamy, the pan-Indian film will now hit theatres worldwide on November 20, 2026. The announcement came with a striking poster featuring Dhanush and Mammootty in a gritty, blood-splattered setting, immediately setting the tone for a film that appears to be aiming for scale, intensity and high-octane action.
Sharing the announcement on social media, Wunderbar Films wrote, “The Day for the Ultimate Strike is Here #OM Hits theatres worldwide on November 20, 2026. A @Rajkumar_KP Film.” The post also tagged the film’s principal cast and crew, including Dhanush, Mammootty, Sai Pallavi, Sreeleela and Naseeruddin Shah. With such a strong ensemble attached to the project, OM has already generated considerable curiosity among fans across different language industries, particularly because it marks an interesting combination of talent from Tamil, Malayalam and Hindi cinema.
The film is being presented as a pan-Indian action drama with the poster carrying the intriguing title Chapter 1: The Blood Wood. Dhanush and Mammootty are seen in an intense avatar, with weapons in hand and a dark urban backdrop adding to the atmosphere. While the makers have kept several details of the story under wraps, the visual campaign suggests that the film will revolve around a dangerous and action-heavy chapter. Rajkumar Periasamy, who previously directed Amaran, is returning with a project that appears to take him into a much larger cinematic world.
OM Chapter One features an impressive cast beyond its two leading men. Sai Pallavi, Sreeleela and Naseeruddin Shah are part of the film in important roles, adding further star power to the project. The film is produced by Shraddha Agrawal, Dhanush and Azmat Jagmag, with music composed by Sai Abhyankkar. RTake Studios and Wunderbar Films are backing the project, bringing together production and creative teams from across the Indian film industry. The combination of Dhanush and Mammootty remains one of the biggest attractions, with audiences waiting to see how the two actors share the screen in this action-driven story.
The announcement of the November 20 date also puts OM in a busy theatrical period, making its release one of the major dates to watch towards the end of 2026. The film’s arrival will give audiences another large-scale South Indian production to look forward to during the festive and year-end movie season. With its multilingual appeal, established stars and an action-oriented promotional campaign, the makers are clearly preparing the film for a wide theatrical rollout rather than restricting it to a single regional market.
For Dhanush and Mammootty fans, the wait now has a definite deadline. OM Chapter One is set to arrive worldwide on November 20, and the first poster has already offered a glimpse of the hard-hitting world Rajkumar Periasamy is creating. With Dhanush and Mammootty leading the charge, Sai Pallavi, Sreeleela and Naseeruddin Shah adding to the ensemble, and Sai Abhyankkar handling the music, the film is shaping up as one of the notable pan-Indian releases of the year. For now, the makers have made one thing clear — the countdown to the ultimate strike has officially begun.
