Analysis of information sources in references of the Wikipedia article "Hinterland (TV series)" in English language version.
In an effort to make "Hinterland" more broadly appealing, every scene was filmed twice: once in Welsh, and once in a combination of English and subtitled Welsh. The all-Welsh "Y Gwyll" (which means "The Dusk") ran last year on S4C, followed by the alternate version, "Hinterland," which aired in Wales and the rest of Britain and features actors reflecting what conversation sounds like in predominantly bilingual far-west Wales.
