The linked video (cinemastix) runs through the ideas (which others had come up with) and how they’re actually applicable to Star Wars because Lucas said they were actually more like silent films, based more on their music and visuals than dialogue.

Now no one needs to be told the dialogue in Star Wars isn’t the main attraction … but I’d never thought about them as silent films let alone actually watching them that way. I’d kinda be into trying that out, at least maybe for ESB.

And then there’s the idea of a Black and White samurai version of the prequels! Which is a thing (with Japanese dub) … and well that actually looks legit!
