The French film Caché (“Hidden”) is a stylish thriller tiptoeing around a psychological drama that lurks inside a political allegory. This is typical of the work of Austrian writer-director Michael Haneke (Code Unknown), who enjoys presenting confrontational films in which seemingly normal folks leading normal lives turn out to be not very normal at all.Caché, which won the Best Director Award at last year’s Cannes Film Festival, stars the enigmatic Daniel Auteuil and the luminescent Juliette Binoche as Georges and Anne Laurent. He hosts a television talk show about books; she is a writer who works in publishing—until an anonymous two-hour videotape interrupts their lives.
