Not so in the past.
This historical mistake dealt a disservice to the real-life Officer William Murdoch, the RMS Titanic’s first officer. In the film, he is depicted shooting multiple passengers while under duress before eventually killing himself. There is no historical evidence that he performed either of these acts, but it was a serious defamation of his reputation. After discovering his error, James Cameron apologised publicly to Rupert Murdoch’s family in the DVD commentary.
