I have not seen the movie, i admit, but i was urged to do so.
It came to mind when i read your question, so i will offer Alexander Sokurov.
His film, The Russian Ark, is filmed in The Hermitage, in Saint Petersburg, Russia, and it consists of one, 96 minute shot.
“The film shows, among other things, the spectacular presentation of operas and plays in the era of Catherine the Great; a formal court proceeding in which Tsar Nicholas I is offered a formal apology by the Shah of Iran for the death of Alexander Griboedov, an ambassador; the idyllic family life of Tsar Nicholas II’s children; the formal changing of the Palace Guard; the museum’s director whispering the need to make repairs during the rule of Joseph Stalin; and a desperate Leningrader making his own coffin during the 900-day siege of the city during World War II.” Wikipedia
