One of the joys of period-set TV series is all the detailing that goes into them. Watching Mad Men, for instance, is a chance to see an homage to the 1960s and the change in fashion over the decade. Shows like Stranger Things cite pop culture landmarks, including movies and TV shows from the early 1980s. For Netflix's latest foray into period drama, Hollywood, it's a chance to revel in the music of the post-war era. Fans are loving Netflix's Hollywood soundtrack, and all the jazz era goodness spread over its seven-episode run.
The story of Hollywood is fiction. It's a fantasy of what could have been, had the right people come along at the right time, and had the stones to force diversity and change on the industry decades before it came to pass. But for such fictions to feel real, period details have to be dead on, or else, it won't work. For instance, Hollywood makes sure to hand Ace Studios, the fictionalized production house, actual movies made that year. When the movie-within-the-TV-show, Meg, gets nominated for Oscar gold, it goes up against the real nominees from the 20th Annual Academy Awards.
Most important, Hollywood gets the sound of the era right, with pitch-perfect songs that make for a fantastic soundtrack.
