Singapore production company Monsoon Pictures and Dutch filmmakers IdtV Film are joining forces to co-produce $6.5m drama Nadra.

The project, which marks the first co-production between Singapore and the Netherlands, tells the true story of a 13-year-old Dutch girl at the centre of a fierce custody battle between her birth parents and Malay adoptive mother.

The controversial case erupted into riots between Muslims and Christians in 1950s Singapore.

Dutch director Ben Sombogaart, whose credits include foreign-language Oscar-nominated Twin Sisters, will direct the project which will be filmed in English, Dutch and Malay.

Production is tentatively scheduled for mid-2008 in the Netherlands, Singapore and Malaysia.

Amsterdam-based A Film Distribution has already pre-bought Benelux rights, while Singapore rights have been sold to Golden Village Pictures. The film is supported by the Singapore Film Commission (SFC) which awarded it a development grant in 2006 under the Project Development Scheme.
