Oscar nominee Michelle Williams has joined the cast of Lukas Moodysson's Mammoth, opposite Gael Garcia Bernal.

The Swedish auteur makes his English-language debut with the project, which starts shooting Nov 5 in Thailand before moving to the Phillipines, Sweden and New York.

Lars Jonsson of Memfis Film will produce.

'In Michelle Williams I feel that we have found the perfect actress for the part of Ellen, and the perfect match for Gael Garcia Bernal,' Moodysson said. 'She relays intelligence, poise and presence in every character she plays. For me,her role in Brokeback Mountain is one of the most honest portrayals on screen.'

Bernal and Williams play a successful New York couple who rethink their lives on a trip to Thailand.

Avy Kaufman serves as US casting director. Williams is represented by CAA 's Hylda Queally. Vibeke Windelove brokered the deal on behalf of Memfis.
