I found this series on the history of comics on film, and appropriately it begins with "The Adventures of Captain Marvel." This series provides good insight into the movies, as well as clever referencing of other comics and comics on film in each episode. Wonderful use of the medium too!
Sadly, the producer won't allow embedding, but follow the link:
