I have not seen the Swedish version but gather it was altered for US release. The end of the US print appears to have been tampered with. The US release was available through Alpha Blue and ran 72 minutes and was distributed by Jerry Gross. Hats off to Synapse for bring us more pristine Lindberg!
The Swedish release of this has a preliminary release date sometime this month according to Swedish webshop Dischop.se. It's listed as having Swedish mono, 1.37:1 aspect ratio and the listed extras include a trailer, exclusive interview with Christina Lindberg and director Gustav Wiklund, picture gallery, easter egg and two tracks Christina Lindbergs recorded for a 7" single.
