HBO Films and BBC Two have joined forces to make Tsunami, an ensemble drama about the disastrous flood that devastated the Andaman Coast in Thailand in late 2004, says Variety. Tim Roth, Chiwetel Ejiofor, Sophie Okonedo, Toni Collette, Hugh Bonneville and Gina McKee will star. Bharat Nalluri is directing. Filming has just begun in the Thailand locations of Phuket and Khaolak. The film will premiere on the HBO and BBC Two at year's end. Tsunami covers the disaster and its aftermath from the vantage point of survivors, media and relief workers. Abbi Morgan (Sex Traffic) wrote the script and Finola Dwyer will produce. Jane Featherstone and Derek Wax will executive produce.
