On YouTube is a French documentary, in English, about comic books that’s from a 2002 UK DVD, when the first Spider-Man movie was released. It’s called Once Upon A Time The Superheroes, and I haven’t watched it yet, but from a quick scan it looks pretty good, although not in the league of Jonathan Ross’ In Search of Steve Ditko. I’ve put together a playlist that assembles the ten parts.
(Did you notice what’s strange about the opening moments?)
