Thanks for that, that's a great help.
I'm tempted to collect these ones, but since
Vampire Circus came out on Blu-ray I'm thinking of holding off to see if they release the others as well.
I have also noticed that they do a three box set containing
Vampire Circus,
The Curse of the Werewolf, and
The Evil Of Frankenstein. At just under 20 Euros it sounds like good value, but I don't know what the packaging is like ie. is it just the 3 standard releases in an outer sleeve?
