The King's Choice - the sinking of the Blucher:
I think this is pretty good but on the IMDB someone points out that 'The rate of fire from the smaller guns on the Blücher is demonstrated to be around 500 rounds a minute; the cyclic rate of fire of the smallest mounted guns was only around 120 rounds a minute.'!!!!
Generally this is a good film on one aspect of the invasion of Norway, an unusual subject for most of us.
