Tsunami, a bilingual film in Hindi and English to be directed by award-winning filmmaker Ujjal Chatterjee, will pay homage to thousands swept away by the killer waves in 2004.

The film will set a love story around the devastating tsunami and a portion will focus on unsung heroes like a priest in Tamil Nadu who gave shelter to hundreds of victims.

Actors Aamir Khan and Rani Mukherji are expected to play the main roles, and superstar Amitabh Bachchan could possibly play the role of a senior geologist or a priest. "People have woken up to issues like global warming and important events like the tsunami, which will forever remain embedded in our minds and that is why it makes an interesting subject to film," Chatterjee said.

The film revolves around three main characters: a geologist who travels to Bali to study tectonic movements when the tsunami strikes, and his former girlfriend and her husband, who get separated during their honeymoon in the resort.

"After months of search, the geologist finds his former love, traumatised in a camp after her husband leaves Bali losing all hope of finding his wife," revealed Chatterjee.
