Some of the more interesting things I thought he said included: "The Victorian Era is often mischaracterized as being stuffy and repressive but really, it was an extraordinarily exciting time in human development and the Industrial Revolution. You had the birth of electricity, of cinema and photography and science was being turned on its head in all kinds of ways. There was huge changes in everything and the world was made smaller for the first time."
He's wrong on photography, which was going strong by the Civil War days and before.
This documentary is very slanted in the secular outlook on everything. Nolan extols the fact that "evolution" was being promoted and actor Hugh Jackman claims that "there were more spiritualists, those dealing in the occult, than there were Christians in America, at this time." I doubt that very seriously since America was almost all Christian its first few centuries.
Nolan and the actors interviewed all agreed that the art of deception, of making a living by "conning" others was interesting and still a very concept that's with us today. One listens to this gibberish and you get a keener sense of just how the secular world of filmmakers think. To then, "science" is everything
I found the rest of this documentary more interesting as they discussed how big "advertising" was back in the Victorian Era with posters everywhere and showed how they transformed Los Angeles back into time,
Most of the rest is technical talk about camera work. The documentary also plays tribute to Tesla, one of the most interesting inventors of all time, a man who dealt with electricity and who is part of this feature film.,
