Lord’s book was my intro at an early age. Have always thought myself to be “in the know” as a result of that reading. Was a member of the Titanic Historical Society in the early 90’s. The details can wear you out. As for the movie under discussion, I’ve enjoyed it while trying to distance myself from the artistic liberties. The story line is decent, if not false.
Off-topic even more, but tangential to talking about Walter Lord.
He also wrote a very good book, “the Dawn’s Early Light”. Excellent reading about the battle of Baltimore (no, not “Ft. McHenry”, the entire thing, plus Bladensburg and DC).
If you haven’t, you should.
He was a Baltimore guy, as I recall.
