Apologies if I offended with my comment ... generalising about a country's taste isn't good. Just basing my idea on the fact that so many hit European movies get remade (usually inferior) by the USA, rather than pushing distribution of the original film with subs. But that's the commercial side of things, rather than artistic.
Back to 'The Price of a Man' aka 'The Ugly Ones' ... I doubt audio rights come into it, as the picture quality on this release looked like an xvid rip with heavy blocking/pixelization ... the print has the same credits as the Spanish version with the original title in both English and Spanish. I can't seriously think that W.E paid anything for this release. It was really disappointing, as it's a top SW, and deserves to be restored and resurrected, a lot more deserving than some of the real stinkers that get pin sharp Blu Ray releases.
If it was a case of audio rights being too expensive, how did they manage to secure an interview with the film's director Eugenio Martin, and not a ten second sequence of original audio. Doesn't make sense. To me this release looks like a rip of the old German DVD, with possibly a little sharpening on the image.
I'd personally prefer muted audio with a subtitle than a jarring drop in of non original sound.
