Just wanted to let anyone who might be interested know that the scandinavian release of Immortals is actually the more violent R-rated US version, not cut like the 15-cert UK version.
Found the cuts here:

Compared with my copy and it uncut alright. Costs 99 SEK for the moment. A decent copy with nice visuals. Has 3D version included too. I'd say it's a bargain. ;-)
