“Summer Hours,” a French film starring Juliette Binoche, “tells the story of a family-owned art collection that must be sold off after the elderly matriarch passes away. In a rare close collaboration between a filmmaker and an art institution, director Olivier Assayas and his crew partnered with the Musée d’Orsay in Paris and several private collectors to locate works ranging from 19th century Barbizon school paintings to rare 20th century furniture.”
