[1] As was established in the books, the recordings took place in Katthult in Kalmar län (part of the historical Småland), Sweden.
The Swedish voicing for the show with subtitles became a big success throughout Scandinavia, with the opening theme and the phrases Förgrömmade unge ("Damned that child") and Snickerboa ("Crafting outhouse") becoming standard phrases even in non-Swedish-speaking areas until well into the 2010's.
In Norway it aired on NRK1 and became a big enough success that re-runs were run until the 2000s and eclipsed the films in popularity.
The scene in episode 3, Kalaset i Katthult, where Emil hoisted Ida up to the top of a flagpole, was cut in NRK's broadcasts, to the dismay of the Swedish production team.
[1] There are no records of the show airing in Finland, where the films remained the main way to watch the franchise.
