[1] The likeness with Donald Duck is only feather deep, however; the comics often take place at a bar, Zeke's, where Arne gets drunk while he cynically thinks about and discusses life.
Some distinct features about Arne Anka[2] are his deep love for Swedish poetry and literature, his miserable financial situation, his excessive consumption of alcohol, and his enthusiasm towards women - even though he has very little luck with any such connections.
For Joachim Trier's 2021 Norwegian film The Worst Person in the World, Charlie Christensen was hired to do the comic "Gaupe" (roughly "Lynxie") in an Arne Anka-inspired style.
[3] In 1990, the Nordic division of the Walt Disney Company ordered Christensen's publisher to cease and desist all publication of Arne Anka, due to the character's resemblance to Donald Duck, and threatened to sue if they didn't.
[4] As a result of all this, the character's popularity soared, as the readers saw him as a hero for standing up to an enormous American corporation; Arne became a symbol of Swedish pride and defiance.
