Honestly, I've been to the movies often here in Sweden and I never heard those Swedes laugh so hard before. And I laughed along with them because this comedy is actually great. It is absurd and makes me think of a Swedish Monty Python movie. Never saw a biography being told in such a ridiculous way either. And even if the movie is Swedish you actually don't have to read subtitles. The spoken language is ridiculously absurd as well. Spanish, English, German, French, you name it, you will understand it.
The only real Swedish is spoken by the narrator and even that text is funny.
Brilliant comedian Gösta Ekman & a bunch of other Swedish actors doing a good job. Rent it.
