Isabelle Huppert, the acclaimed French actress who won the acting Palme at Cannes earlier this year for Austrian film The Piano Teacher, is to head the cast in iconic German director Werner Schroeter's next project.

Schroeter's untitled project is the life story, from infancy to 45 years of age, of two twins who were separated at birth, but whose lives remain intertwined. Bulle Ogier, recently seen in Venus Beauty (Institute), will co-star.

Principal photography is scheduled to start in November in Paris and Lisbon. The picture is structured as a co-production between Paulo Branco's Gemini Films company in France and his Portuguese outfit Madragoa Filmes. International sales are handled by Gemini.

Schroeter became one of the leading figures of the 1970s German new Wave movement and Huppert was the star of his most acclaimed work Malina in 1991. That film was scripted by Elfriede Jelinek, the novelist behind Michael Haneke's The Piano Teacher.
