There's a scene from Ordet farmer Morten shouting "Johannes, Johannes..." in the middle of field.
Next scene Rita Hayworth waving her hand on the screen.
If you expect to know cinema history in here, then it's not a right place for you. Godard played with clips of cinema history and sounds without any explanations. Wait, may be there is a logic.
Godard coming in the screen smoking his cigar and says to you ,"Well , what do you expect? To know history without watching cinema. That ain't gonna happen here. First watch cinemas, then come back."
Well, he didn't say those words.
How can you think to say that to you? It's Godard, man.
He didn't want waste time for you.
He was probably thinking about his next jump cut.....
