Just watched this excellent movie, about Vidkun Quisling. The actor who played him was phenomenal, and it was a very powerful film, with a strong Christian message.
Quisling: The Final Days

I’m guessing you likely have, but watch “The King’s Choice”
About the German invasion of Norway. Remarkable as one of the very rare successful times that coastal artillery sunk attackers. The 8 inch German Cruiser Blucher, sister ship to the Prinz Eugene, was sunk. She was hit twice with 11 inch shore guns, and two shore launched torpedoes! Great battle scene in that film.
