Notable can mean many things. Maybe it was high quality, insightful, and provided context for a more artistic scene. Maybe they teased a cut scene that would have radically shifted the tone of the movie. Maybe it was funny. Maybe the director absolutely hated what they produced and is only providing narration because of a contractual obligation and a lot of alcohol.
I am looking to hear about anything that stuck with you in some way.
A lot of people consume content online where director’s commentary frequently isn’t present but I imagine there are still a lot of people who are into this niche.
The Lord of the Rings has like four goddamn commentaries per movie, from the director, the actors, the scenic designers, and the composer Howard Shore, and who knows maybe I’m forgetting a couple. I love hearing the cast because you can alternately hear about what gigantic dorks they are for the material or how incredibly thoughtful they were. I recall hearing Sean Astin get way into political philosophy and how Two Towers was emphatically not a pro-war movie.
The Matrix has philosopher commentaries where Cornel West and Ken Wilber talk about the heavy duty concepts being explored. The fun part is that they seamlessly go back and forth between philosophy and action movie appreciation, where they’ll say stuff like "So you’ve got to remember that in Plato’s allegory of the cave the observer is always— oh shit she just kicked that guy in the throat!"
