Real-life lovers Liev Schreiber and Naomi Watts have been cast opposite each other in romantic drama The Painted Veil.

THE MANCHURIAN CANDIDATE star Schreiber, 38, and Watts, 37, flew to Shanghai, China together to begin work on the JOHN CURRAN-directed film, which also stars Ed Norton.

Schreiber and Watts began dating in May (05) after meeting at the Museum Of Modern Art's Costume Institute Gala in New York.

Oscar-nominated Watts is also co-producer on the film.
