This video from "Every Frame a Painting" about 'F for Fake' is good as well: https://www.youtube.com/watch?v=1GXv2C7vwX0
The Akira Kurosawa one, the Ensemble Staging one, the Satoshi Kon one, the Wolf Children one are some of my favourites.
Nerdwriter1 does similar stuff but it's a bit more hit or miss for me. Some of it I love, versus some is a bit too out on a limb.
Compared to Every Frame a Painting who seems to release videos when he finished it.
