horse and rider: a movie question

i have a cinema question! a few years ago i was in france and they showed this old soviet (?) silent film about this old man in a village who builds his own coffin and nails himself inside. during the whole process, it shows these black horses approaching, the camera focusing only on their legs, and as he gets closer to finishing his coffin, the horses get closer to the village, and as he climbs in the coffin, the camera moves up to focus on the riders of the horses, who are hideous pig people with hideous pig faces. it was the most terrifying thing i’ve ever seen in my life, i actually started screaming, and i’ve never been able to figure out what it was called. 

pls reply with answers!!!!
