According to anecdotage.com, the aptly titled “Cure for Insomnia” is the longest film ever. It runs about 87 hours and features L.D. Groban reading a really looooong poem. Just in case you find that kind of boring, according to IMDb, the film slices in pornography and music video footage. Probably not the best “date movie.”
“Cure for Insomnia” is best described as an experimental film (i.e., pretentious and without a point). Of all the films with actual storylines, the 1928 Chinese movie “The Burning of the Red Lotus Temple” is the longest, clocking in at 27 hours. As for the longest documentary, “Grandmother Martha” wins with a 24-hour running time.
Should you come across any of these epics at the video store, we recommend you watch them in stages. Many, many stages.
