Overview
- Wunderbar Films announced on Friday that OM – Chapter 1: Udhiram – The Blood Wood will open in theatres worldwide on November 20, 2026, and released a new poster featuring Dhanush and Mammootty.
- The film was moved from its original October 16 date after Dhanush said the team wanted to avoid clashing with Rajinikanth’s Jailer 2 and to stay out of the Deepavali window where other star releases are scheduled.
- Director Rajkumar Periasamy has said roughly 60–65% of filming is complete and the unit recently shot sequences in Malaysia, indicating production and postwork will continue through the new release window.
- Titled as a ‘Chapter 1’ and billed as a mass‑oriented action drama, the film pairs Dhanush and Mammootty for the first time and also features Sai Pallavi, Sreeleela and Naseeruddin Shah with music by Sai Abhyankkar.
- The new date protects OM’s box‑office window and gives the team time for marketing and finishing work; box‑office observers will watch how the late‑November slot affects turnout for a planned two‑part franchise.
