Recommended. Simon (Kacey Mottet Klein, Home) is a 12-year old hustler and thief who ascends each day to the posh ski resort perched above his bleak Swiss apartment complex and steals from the rich. Sister presents him as a Truffautian street urchin, charming and resourceful, supporting his indolent older sister, Louise (Léa Seydoux, Blue Is the Warmest Color). We think we get these kids until halfway into the story a revelatory plot twist throws everything into a snowbank. I screened this based on Ms. Seydoux’s talented blue-headed performance and was not disappointed. Both leads create complex and fascinating characters under director Ursula Meier’s (Home) nuanced eye, suggesting that highly risky families can also share love. Gillian Anderson has a small but crucial part, which she aces, possibly representing the viewer’s eye. Sister was Switzerland’s submission for the 2013 Foreign Language Oscar. It made the short list, but was not nominated.
