Scener ur ett äktenskap (1973)

• Lasts 2.5 hours but you feel it like 20
• The trailer lasts 20 minutes
• There is a “Special Edition” that lasts around 8 hours and no living person has ever been able to watch it entirely.
• It´s basically two persons engaging in small chat (chin wagging) , silly moaning and very occasional kicks in the stomach area.
• According to the interview with Ingmar Bergman, after the original TV mini-series version of the film was broadcast in Sweden, the divorce rate in Sweden increased substantially and the number of married couples who seek marriage consultants also doubled. (Source: IMDB)
• It has no zombies and doesn´t end in anything like  ” …of the dead”
• Around the film´s release in American soil IKEA Furniture successfuly marketed a double bed (model Ulmaen) that could be split in half during marital existential-crises periods. The bed was widely adopted in Manhattan´s Jewish neighbourhoods (Citation needed)
• Almost  forgot, THERE IS A SEQUEL

… Or you can put yourself to work since this is not a vacation
