How do I decorate my room in a vintage film-inspired style that's a bit edgy?

I just got a new house and wanted to decorate my bedroom in a vintage style, but with an artsy edge. I kind of wanted to incorporate a 1920s glamor style with the dresses, vanity chair etc, but also a 1960s style with things like andy warhol - kind of breakfast at tiffany's inspired. but i also wanted to make it a bit edgier, with kind of surrealist salvador dali-ish elements, and maybe some james dean. I want my room to be film-inspired, so maybe i could have some vintage film posters? I kind of have all these ideas but don't know how to incorporate them into one bedroom. If you have any suggestions about textures or color schemes that would be great. Also, I have a walk-in closet and a bathroom, so any suggestions for those would also be appreciated.
