I have never relied much on pedagogical films, i.e. films which themselves lecture on film studies. However, designing my syllabus this time around, a colleague had reminded me of a Noel Burch film/TV series, Correction Please, which really is a wonderful explanation of the development of narrative storytelling in cinema. Unfortunately, the film has never had a video release and only a smattering of university archives, departments and libraries have a closely-held copy. So far, I've been unable to obtain a copy anywhere.
The larger question I have is: what other useful pedagogical films might I be missing. Burch may well be an unusual case, as theorist and filmmaker who also took on the mantle of popularizing an genre overlooked in the larger film culture.
For that matter, are there any useful multimedia educational materials worth using? For all of the supposed media savvy and literacy of pop culture scholars, there's some pretty dire stuff I've seen. Then again, things can change a lot in a short time.
