I didn't say he gave them names but it is known fact that he provided core extras with some stories that were from survivors accounts. Therefore there it may be easy to indetify (only for Trivia) which survivor/victim it may be. The mini-series is mostly inaccurate.
For what? I mean it will be lower quality than even DVD because the YouTube decreases everything. It can't match even DVD and hardly Blu-ray. Besides it could be one day blocked by owners and won't work anymore.
According to Episode 2: Murdoch tells Annie Desmond that First Class is booked solid (which it wasn't in real life), the number for full First Class Passengers would have been 833. The Titanic had 324 in First Class when she left Queenstown.
Once the Titanic mini-series gallery is completed with First Class Passengers and servants, we can see if the numbers add up to 324 or 833.
Not all of them played people on the Titanic; you had the protestors and workers fitting out the Titanic in Episode 2, Scots guards in Episode 3, policemen and prostitutes in Episode 1, and the people in Southampton passing by during the boarding scenes.
