Not only is the trailer for Tout en Haut du Monde (aka Longway North) awesome, but the film is written by two women: Patricia Valeix and Claire Paoletti. Also working with them is a principal artist from Secret of Kells, which is just fantastic.
Synopsis from IMDb:
“Sasha, a young Russian aristocratic girl at the end of the 19th century, dreams of the Great North and languishes over Oloukine, her grandfather. He is a renowned scientist and Arctic explorer, who has not returned from his last expedition to conquer the North Pole. Oloukine has passed down his passion to Sasha, which is far from satisfying to her parents as they have already arranged for their daughter to marry. She revolts against this destiny, flees and is resolved to rejoin Oloukine a Longway North.”
