Spanish Blu Ray BBC
I found the blu ray on Amazon Spain for a lot less than Twilight Time one at $40. Granted it's BD-R mod as opposed to the pressed disc. It's also region B requiring a region free player. It just may be a copy of the Twilight Time disc.
The audio is Spanish or English. It plays beautifully.
They also discount the VAT tax when shipping to the USA. I got the disc for 6.92 Euro, not counting shipping. I bundled it with several other Spanish blu-rays of American Films.
