Where La La Land was shot in LA, scene by scene
This is a cool little interactive piece from The LA Times. Going through this list, it's a bit remarkable to me that I've been to so many of these places. I miss LA, but I don't know when I'll be there again.
The Cinematography of La La Land
This has lately been my favorite YouTube channel to just put on and sit back and relax to. This guy basically breaks down music videos and movies from a filmmakers point of view complete with in-depth analysis of cameras, camera movements, crew, and post-production work.
SoundWorks Collection: The Music of La La Land with Composer Justin Hurwitz
Watch the wonderful video above from SoundWorks Collection about how the sound of La La Land was made by composer Justin Hurwitz.
On a related note, I just discovered on Spotify that La La Land has a 44-track extended soundtrack available called "La La Land - The Complete Musical Experience". It's much more fun to listen to than the standard soundtrack and you can hear the whole album below.
