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.
This is Spinal Tap. The cast does the commentary in character, as if they’d just discovered many years later that Rob Reiner was making fun of them rather than it being the serious documentary they thought it was. They spend the whole movie talking shit about him and it’s hilarious.
Anvil: the Story of Anvil. Such a touching movie by itself, the commentary by the director, a childhood friend of the band, adds more depth and pathos to the story. My wife and I watched the movie and then rewatched it immediately with the commentary even though it was past midnight and we would normally be in bed. The story is just that gripping.
Second the mention of Tropic Thunder made in another comment. RDJ improvising the whole commentary in character is amazing and will increase your estimation of him as an actor, if that’s even possible.
