After Kaathuvaakula Rendu Kaadhal, Nayanthara is back with another release. Titled O2, the mystery thriller is directed by GS Viknesh. The film skipped theatrical release and premiered directly on Disney+ Hotstar. The film has been receiving positive reviews from the critics and audience alike. Among the technical team, cinematographer Thamizh Azhagan's work has been appreciated by man. Since most of the film takes place inside a trapped bus, it takes a lot of effort to light the frame and show accordingly.
In a statement, Thamizh said, "Director GS Viknesh is a close friend. When he narrated the script back in 2019, is when I started journeying with it. I was keen on delivering visuals to the audiences which will help them believe in the real essence. In particular, with Dream Warrior Pictures adding Midas-touch to the project, I started working intensely to deliver the best. Although set works were erected for Landslide and Bus scenes, I wanted them to look so real that the audiences shouldn’t feel it's a set. Besides, I wanted to make sure that the audiences feel the urge to survive among the onscreen characters as well while watching the movie. I started preparing for 'O2', around 2019, even before the commencement of the shoot. Every single scene was visualized first, with appropriate detailing, lighting graph and was finalized before going to the set, which has helped deliver a positive output."
