Actress Pooja Kumar, who has featured in films like "Flavors" and "Anjaana Anjaani", has performed her own underwater stunts for Kamal Haasan's upcoming multi-lingual action-drama "Vishwaroopam 2".

"(I) just arrived back to New York City (NYC) from shooting in Bangkok with 'Vishwaroopam 2' team. I did all my underwater stunts as I am a certified scuba diver," Pooja posted on her Twitter page.

In the film, Pooja plays Nirupama, a nuclear oncologist and wife of Kamal Haasan's character, a RAW agent. The movie is currently being shot in Bangkok.

The film is the sequel to highly controversial yet successful "Vishwaroopam", also written and directed by Kamal Haasan.

While the prequel was shot in Afghanistan and the US, the sequel is said to be predominantly shot in India, including few places abroad.

"Vishwaroopam 2" also features Kamal Haasan, Rahul Bose, Andrea Jeremiah, Jaideep Ahlawat and Shekhar Kapur.
