This coming-of-age film with a difference presented the following challenge for synchronisation:
Much like the Groundhog Day principle, our protagonist experiences the same day over and over again, but with minor variations.
This meant that the dubbed dialogues always had to sound the same except for these little variations, as in “Spot the difference”.
