The Living Force
From the description of the movie:
Animated short film in which Mrs. Tutli-Putli boards a night train, dragging all her belongings with her. Traveling alone, she shares her cabin with strangers, sometimes benevolent, sometimes threatening. When night falls, she finds herself at the heart of an anguishing metaphysical adventure, where reality merges with dreams. Jungian thriller? Hitchcockian suspense? An artistic tour de force? Get on board, the night train is waiting for you...
Mrs. Tutli-Putli is the winner of several international awards. It was also nominated for an Oscar in 2008.
