I've just watched 'George Gently', set in 1964. It occurred to me that it wasn't just retro - maybe people watching it wanted to pretend it was current and it was 1964! The attention to detail in car models, watches etc is remarkable.
It's also interesting that the 1964 device allows the filming of books written before mobile phones and CCTV whose existence could stuff the plot.
Louise Brooks... There was a nice write-up on her in The New Yorker. See if you can find that and have a read; it has some interesting insights into her life and times. Not much of an actress but a tigress in the sack... or something like that, I think. Go have a read.
If you are into this sort of thing then check out the art of Tamara de Lempicka. Same era as Louise Brooks, a highly talented painter, she generated many striking images that should appeal to someone who likes the looks of Ms Brooks. You often see her paintings used as cover art for books, such as "Chrome Yellow."
Mind you, being gay, gay, gay really helps one to get into this groove, since much of it was about the glossy surface, the look of things at a time when the substance was going to Hell in a handcart.
I am just a humble hetero so that I stand there dropping hayseeds onto the gallery floor, gawping at the polished sophistication on display, my only solace for not being any part of it being the idea that many of these idols must have ended up in a studio flat in Manhattan with just a few dozen cats for company after the short, ephemeral career faded.
