Veteran actor Mammootty spends about two and a half days listening to the script before filming begins for Rajkumar Periasamy’s film titled “OM,” the director says. Periasamy adds that Mammootty invited him to Kochi for an extensive narration as part of the preparation process.

Both outlets report that the actor uses the sessions to get a detailed understanding of the story and his character, including questions raised to clarify aspects of the narrative. Times of India further frames this preparation as Mammootty arriving on set “fully prepared,” and links the film’s title to plot elements involving operations associated with Sai Pallavi’s character, alongside a strong spirituality theme. NDTV emphasizes the director’s account of the long narration and the Kochi visit, focusing more on the behind-the-scenes preparation.
