The cast and characters
Dhanush leads the film and also co-produces it through Wunderbar Films. Malayalam star Mammootty shares the screen with him, a pairing that has drawn strong interest from fans in both Tamil Nadu and Kerala. Sai Pallavi plays an IPS officer named Nithya Reddy, according to Filmverse. Veteran Hindi actor Naseeruddin Shah and Telugu actress Sreeleela are part of the supporting cast.
About the director
Rajkumar Periasamy’s previous film, Amaran, starred Sivakarthikeyan and Sai Pallavi and was based on the life of Major Mukund Varadarajan, an Army officer who was posthumously awarded the Ashoka Chakra. It was one of the biggest Tamil hits of 2024, which has raised expectations for his next project with a bigger cast.
A two-part story
The makers have described OM as a pan-Indian action thriller and the first part of a planned two-part franchise, Filmverse reported. The film was first scheduled for release on October 16 and was later moved to November 20.
Producers listed include Shraddha Agrawal, Dhanush and Azmat Jagmag, with Sreyas Srinivasan and Sandesh Agrawal as co-producers.
Why the trailer is trending
Big Tamil films with multi-star casts have found large audiences across India in recent years, and the Dhanush-Mammootty combination is a first. Sai Pallavi is also on screens as Sita in Ramayana, which has crossed Rs 1,000 crore worldwide, as we reported in Ramayana box office collection.
Will OM release in Hindi?
The makers have promoted OM as a pan-Indian release, but the full list of language versions has not been confirmed in the reports we checked. If a Hindi version is released, it would likely get more shows in Pune than the Tamil original. Check ticketing apps closer to November 20 for language and show timings.
