Russian Ark (Russian: Русский ковчег, Russkij Kovcheg) is a 2002 historical drama film directed by Alexander Sokurov. It was filmed entirely in the Winter Palace of the Russian State Hermitage Museum using a single 96-minute Steadicam sequence shot. The film was entered into the 2002 Cannes Film Festival.[2]

An unnamed narrator wanders through the Winter Palace in Saint Petersburg. The narrator implies that he died in some horrible accident and is a ghost drifting through the palace. In each room, he encounters various real and fictional people from various periods in the city's 300-year history. He is accompanied by "the European", who represents the Marquis de Custine, a nineteenth-century French traveler. Russian Ark uses the fourth wall device extensively, but repeatedly broken and re-erected. At times the narrator and the companion interact with the other performers, while at other times they pass unnoticed.
