Some of the seventeen great introductions by Odie Henderson to his Black American Cinema series at Off Plus Camera IFF were filmed.
Enjoy Odienator as he introduces Shaft here and Jackie Brown here. These are full videos of entire intros.
Parts of other intros were captured thanks to lensers Joanna Konik and Karolina Waschto (aka the Tablet Lady):
