Somewhat off topic, but I saw Norsemen mentioned elsewhere in the thread ... Norsemen was filmed simultaneously in Norwegian and English (the actors did each scene in one language and then the other). That way Norwegian audiences can enjoy this expensive-to-make show in their native tongue, and it can also gain widespread popularity in the much larger English-speaking world (which pays the bills). I recently read that Hinterland (aka Y Gwyll) did the same with Welsh and English. Anyhow, is there a name for this technique of producing a show in multiple languages simultaneously? Any other examples of it? It seems like a good idea for producing high-quality content in languages that otherwise wouldn't necessarily attract that level of investment.
