Ostensibly more fictional than Moretti’s other films, Bianca focuses on a lonely young mathematician working at the ridiculously hip and liberal “Marilyn Monroe High School.” A control freak obsessed with idealized notions about happy family life, he meddles in his friends’ affairs in desperate attempts to prevent them from splitting up. When he falls in love with the woman of his dreams—the new French teacher—he comes to realize that the neat logic of math fails in matters of the heart. With his trademark dark humor, Moretti wryly wrestles with the cosmic condition.
