Mera Naam Joker (1970, 4 hours, four minutes)
That Raj Kapoor liked his sagas long was no secret, but he outdid himself with this melodramatic story of a circus clown. Audiences at the time didn't buy into the two-interval film and it bombed. But, a few decades later, Mera Naam Joker is looked on with fond affection for the great showman.
The length: Like three films strung together back to back, the greasepaint tales of Raju the clown were always too long for a single shot. Add that it was a heartbreakingly tragic film and you get something that exhausts both handkerchiefs and viewers.
