on the second part of Irène Némirovsky's 2004 novel of the same name. In the film, she played a woman falling for a German soldier during the German occupation of France during World War II, a role which Leslie Felperin of The Hollywood Reporter found "underwritten".

I didn't want her to be sitting around waiting for someone to come save her but also to be, in the meantime, fixing the problem herself." Reviews of the film were generally unfavourable, but Manohla Dargis of The New York Times credited Robbie for "holding her own" in her
