Good quality & good clear (& essential) subtitles.
No cast list in the film, or on the DVD box - would have been helpful.
The description on amazon.uk had no information about subtitles or language, & until the DVD arrived I had no idea whether it was dubbed or in the original languages (French & Italian mainly) - I was relieved to find it was in the original languages.
For the price I would have expected some extras - for instance, a (quite cheap) French version, previously bought from amazon.fr, included a DVD about the technical production of the "Farinelli voice", which was fascinating. But purchasers of this DVD would have remained in ignorance of the whole complex process.
