I loved this. Unusual drama set in 1402, not long after the vain and brittle Richard II had been deposed by Henry Bolingbroke - Henry IV, the first monarch whose first language was English not French. This is factored in here with a visit from the English court.
Lots of machinations and sly manoeuvring by all interested parties, royal and otherwise. Interesting history, wonderfully filmed in various languages. The foundation of Scandinavia indeed. My advice is CONCENTRATE as the goings-on and shifting loyalties could be confusing if you miss a bit (I rewound to reread subtitles several times).
There are other imposter dramas - and this is largely fiction though based on a real case (which I had never heard of before). Reminds me of Perkin Warbeck who in late 15th C claimed to be the rightful king of England (he wasn't).
The actress playing the devious, self-serving queen is superb and actor playing ERIK is great as well, so I shall try and watch other films Morten Hee Andersen has appeared in.
4 stars.
