I can't judge, because I never saw it. The 1958 movie about the Titanic I saw in the theater. (But only a few years ago, not in 1958. The 1953 one was also good.
There was a Nazi version of Titanic, they made in 1943, which basically blamed it on “British Capitalism”, and the hero was a German crew member who tried to warn them.
That 1958 movie was “A Night to Remember,” based on the book of the same name by Walter Lord. That was a very good portrayal of the events.
