LONDON — Sean Ellis, who won an Oscar nomination last year for his short “Cashback,” has started shooting his second feature, “The Broken,” backed by French major Gaumont.

“The Broken” is a psychological horror project, starring Lena Headey as a woman whose life descends into nightmare after she sees an apparent double of herself driving by in her own car.

The multi-national cast also includes Richard Jenkins, Melvil Poupaud, Ulrich Thomsen, Michelle Duncan and Asier Newman. Producer is Lene Bausager of Left Turn Films, and Gaumont CEO Franck Chorot is the exec producer.

Gaumont is also handling worldwide sales of the feature-length version of “Cashback,” which opens theatrically in France on Jan. 17.
