Right! I have seen the american version too. Neither is a particular good movie. And you should not approach the Swedish film with high hopes of finding something brilliant. You should expect it to be very crass, and see it if you just want to find out what weird shit Swedes create when no one is looking.
There is a Swedish movie called Naked, which is about a guy who gets Groundhog Day’d in the following way: He wakes up naked in an elevator in an apartment building, he is hungover because it was his bachelor party the night before where he was black out drunk, and his friends left him here in the elevator. As a bonus they shoved a condom up his behind. He has a few hours before his wedding.
I have a friend, whom I have like a very small common circle with. For some reason, they mentioned me to a coworker, like “I have this friend who does this and that”, mentioning some strange quirk I have. The coworker goes “Yo, do you mean <my name>?! I’ve met him once!”. Apparently I weirded them out enough to remember me years later.
Ah, but that one is good though :-)
While on the topic… Iron Sky is a Finnish film but in the english language. Quite good. The same creators did Star Wreck: in the pirkinning, a parody movie, this one in Finnish. Too long ago since I saw it to remember if it was funny, mostly odd I think… But they might be something for you then.
