Not so historical
The first officer of the RMS Titanic, real-life Officer William Murdoch, suffered damage by this specific historical error. In the film, he is shown shooting multiple passengers while under a lot of stress before killing himself.
He died a hero, giving up his life jacket and eventually drowning, yet there is no historical evidence to suggest he did either of these things. After criticism, a representative from 20th Century Fox visited Murdoch’s family to express regret for his unfavorable portrayal.
