Catherine Breillat’s Last Summer is a remake of a 2019 Danish film called Queen of Hearts, May el-Toukhy’s feature about a woman who embarks on a sexual relationship with her teenage stepson. This adaptation follows the original closely, down to specific scenes and lines of dialogue. Yet it is a Breillat work in every conceivable way, a challenging, sometimes ecstatic engagement with desire, sex, shame, and power that manages to be strikingly different in tone, emphasis, and conclusion from its source.
