Abbas Kiarostami, the Iranian director.
Here’s the beginning of Under the Olive Trees which has a striking long shot from about 4:00 – 7:00.
And here is a scene from Taste of Cherry. There are a few long takes inside. The man driving wants to kill himself and asks his passenger to come and bury him or rescue him from a ditch the next morning. The old man has a story of his own. There are long telescopic shots of the vehicle going up and down hills and the old man’s monologue is one take, though sometimes interrupted by cuts.
