Mammootty topped Rajkumar Periasamy’s wishlist
Rajkumar Periasamy had a specific group of actors in mind before production began. Mammootty was his first choice for Karthikeyan.“Even before going into principal production, I had a certain wishlist of actors for my cast. The very first pick was Mammootty Sir for the character of Karthikeyan. The same principle applies to all other actors: be it Dhanush, Indrans, Naseeruddin Shah, Sai Pallavi and Sreeleela. When I went to them with the pitch, they readily accepted. I’m delighted with the way things have turned out. And it’s almost complete. Very little patchwork is left,” Rajkumar said in a chat with Variety India.Mammootty’s inclusion gives the movie another major star alongside Dhanush. Earlier, both actors were seen together in the Malayalam film ‘Kammath & Kammath’.

Rajkumar Periasamy discusses release delays
Rajkumar Periasamy also addressed the changes in release dates often seen in South Indian cinema. He explained that several practical factors can affect a movie’s theatrical schedule.“In the case of ‘OM,’ it’s been genuine post-production reasons or the shooting schedules got delayed due to star dates or location permissions. Often, it is because most filmmakers or producers are eyeing the same important release dates. However, we have a limited number of theatres and therefore, if producers cannot get a date of their choice, they wait for the next better option.”Meanwhile, ‘OM’ is now scheduled to reach cinemas on October 16, 2026.
