PETROV’S FLU, directed by acclaimed Russian filmmaker Kirill Serebrennikov,  (LETO) is a deadpan, hallucinatory romp through post-Soviet Russia. With the city in the throes of a flu epidemic, the Petrov family struggles through yet another day in a country where the past is never past, the present is a booze-fueled, icy fever dream of violence and tenderness, and where, beneath the layers of the ordinary, things turn out to be quite extraordinary. Part science fiction, mystery and dark comedy, this Cannes Film Festival entry is a unique hybrid of genres.
