Despite the passage of 60 years I somehow doubt a new big budget Bismarck movie made today would be any more accurate and might be significantly worse.
I happened to have read an analysis of the operation recently in the Naval War College Review and it noted that Admiral Lütjens was not a rabid Nazi though he was portrayed that way in the movie.

I think there are some errors in the article but it does approach the topic from an operational standpoint for the benefit of professional naval officers which is a bit different way of looking at things.
After ranting about the book "Battleship Bismarck" in an earlier post, I found myself rereading "Pursuit: The Chase and Sinking of the Bismarck" by Ludovic Kennedy last weekend. That is a wonderful book - a real page-turner - with all the essential facts in compact form.
Then I also had to rewatch the movie "Sink the Bismarck" from 1960. A good film in some respects, but with a number of errors, I guess to make it more exciting, like Bismarck shooting down one of the Swordfish, and blowing up one of Vian's destroyers. The models used in making the movie looked pretty accurate, but they are shooting on the wrong side in the Battle of the Denmark Strait, i.e., Bismarck is firing to starboard instead of to port, etc.
One other item the reading and watching reminded me is about the actor Esmond Knight, who plays Capt. John Leach of the Prince of Wales. He was actually on PoW during the battle, serving in a fire control position just above the bridge, and was partially blinded by the shell that went through the bridge and killed or wounded several crew. He was active in movies, TV, and the stage from 1928 to 1987, including roles in all of Laurence Olivier's Shakespeare movies.
