Mixing historical realities with a fictional modern discovery is a difficult combination to pull off. Writer/director Gilles Paquet-Brenner is helped along by thrilling source material that is based around a little known event in France’s grim times under the occupation of Nazi control in the heat of World War II. Sarah’s Key is bolstered by an engrossing turn by Kristen Scott Thomas and a swift kick of an ending that will leave audiences with sincere emotion. The film also keeps much of what made Tatiana de Rosnay’s novel so alluring with the back and forth between the present and the past, and the result is pulled off with absolute confidence. Hit the jump for my full review.
