This pleasant atmosphere is spoiled by the arrival of the Men in Grey. These strange individuals represent the Timesavings Bank and promote the idea of timesaving among the population, time which can be deposited to the Bank and returned to the client later with interest. In reality, the more time people save, the less they have. The time they save is actually lost to them, consumed by the Men in Grey. Momo, however, is a wrench in the plans of the Timesaving Bank thanks to her special personality.This film was an ItalianGerman production in which Michael Ende himself played the role of the passenger in the train who is told the story by Master Hora and writes it down.
