'Om': Naseeruddin Shah Joins Dhanush-Rajkumar Periasamy's Film

Veteran Hindi film actor Naseeruddin Shah has joined the team of Rajkumar Periasamy and Dhanush's Om. "A strong addition to the world of #OM The veteran #NaseeruddinShah on board the mega biggie. Coming to cinemas worldwide on October 16th 2026," the makers wrote on X.

Shah, who was last seen in Imtiaz Ali's Main Vapas Aaunga, returns to Tamil cinema around 26 years later with this film, following Kamal Haasan's period drama Hey Ram (2000).

The film's teaser, which was recently released, opened with visuals of mountains, forests, and a temple town, followed by a shift to a confrontation in a rain-soaked jungle. The teaser further showed police personnel holding woodcutters and workers at gunpoint with Dhanush coming to their rescue, leading to an action-packed fight sequence backed by the film's strong score.

The film is written and directed by Rajkumar Periasamy, who previously directed Amaran (2024). This project is his first collaboration with Dhanush. The film’s cast includes Mammootty, Sai Pallavi, and Sreeleela. Music for the film is by Sai Abhyankkar, who recently worked on RJ Balaji's Karuppu, and cinematography by Ezhil Arasu, editing by Kalaivanan R and costumes by Kavya Sriram. The film is produced by Wunderbar Films in association with RTake Studios.

Dhanush’s recent projects include Tamil heist action drama Kara (2026), directed by Vignesh Raja, Tere Ishq Mein (2025), the Hindi romantic drama co-starring Kriti Sanon, and Kuberaa (2025) which featured Nagarjuna, Rashmika Mandanna and Jim Sarbh.

Mammootty returns to Tamil cinema with this film following his blockbuster reunion with Mohanlal in Patriot (2026). He is also reported to be a part of Adoor Gopalakrishnan’s ongoing project, titled Padayatra, a socio-political drama also starring Indrans and Grace Antony.

Sai Pallavi, who was last seen alongside Junaid Khan earlier this year in Ek Din, reunites with Periasamy after Amaran (2024), and with Dhanush after Maari 2(2018), directed by Balaji Mohan. Sreeleela joins the cast fresh after Ustad Bhagat Singh (2026), where she starred alongside Pawan Kalyan and Raashi Khanna.
