True, but I believe italian neorealism didn't have international reach until fellini - outside of influencing french new wave which went on to popularize (within the art community at least) those ideas. French New Wave also paired it with new editing and cinematography techniques that made it all work together.

Edit: I had originally prefaced this with "I'm not a scholar" but forgot to readd it - the responses below invalidate most of what I said, but leaving the comment so their responses make sense - though I still stand by the lesser version of what I said - that Godard had a bigger impact on American cinema than pre-Fellini Italian Neorealism, and that parts of italian film influenced Godard.
