Dhanush, Mammootty and Sai Pallavi Set the Screen on Fire with ‘O.M.’ Trailer — Releasing November 20

Some trailers announce themselves quietly. This one doesn’t bother trying.

The makers of ‘O.M.: Chapter 1 - Udhiram: The Blood Wood’ have dropped the trailer, and it wastes no time stacking star power on top of star power. Dhanush, Mammootty and Sai Pallavi share screen space in what looks like a dense, high-stakes thriller - and judging by the two-and-a-half minutes released so far, nobody’s holding back.

Directed by Rajkumar Periasamy, the film leans into a mix of action, mystery and simmering confrontation. The trailer doesn’t spell everything out, which is probably the point - it gives just enough to make you want the full picture.

Dhanush shows up in a version of himself audiences haven’t quite seen before: rougher, more physical, clearly built for a film that demands he go all in on the action front. Mammootty, by contrast, does what he’s always done best - says less, commands more. His presence in the trailer carries weight without needing to shout about it.

But it’s Sai Pallavi who might end up stealing the most conversation. Playing IPS officer Nithya Reddy, she brings an edge that feels new for her - sharp, unflinching, and clearly central to wherever this story is headed. Sreeleela rounds out the cast, adding her own layer to a trailer that already has a lot going on.

‘O.M.’ hits screens on November 20, and based on this first look, it’s positioning itself as one of the bigger multi-starrer releases of the window.
