I've seen
Headhunters and
King of Devil's Island. The first is with Aksel Hennie, who is an excellent actor. Any of his stuff is worth a watch. I have not heard of the other three you mention.
Oh.
A Somewhat Gentle Man is another with Skarsgard that is very good.
And while we're on this Scandinavian kick, with a Norwegian theme... Have you checked out the TV series
Lilyhammer with Steven Van Zandt and Trond Fausa. Brilliant show. I think it's on Netflix too. Dark comedy about a New York Gangster in witness protection in Norway.

For anyone interested in anime films. Isao Takahata's latest The Tale of Princess Kaguya just showed up on torrent sites a few days ago. Here's a link to a dual audio version, one can choose either the Japanese audio with English subs, or the English audio.

There's a smaller version available as well. Brilliant, brilliant film.
