“A villa in Italy” by French-italian filmmaker Valeria Bruni-Tedeschi provided a welcome dose of charm and comedy yesterday in Cannes. An exultant love letter to her brother, who died of AIDS several years ago, “Villa” is painfully autobiographical, in fact. Besides her brother (played by Filippo Timi) and her real-life mother (to whom former first lady Carla Bruni bears a striking resemblance) as…. her mother, Bruni-Tedeschi also puts her romantic wares on display, casting her real-life (former) lover Louis Garrel, the son of filmmaker Philippe Garrel (the two have since broken up, in 2012) . So many connections
