I understand that this was released in both the UK ("The First of the
Few") and in the USA ("Spitfire"). A review I read on Amazon said
the US release was very low quality but hinted that the UK version was
better.

Two questions: Could I play the UK verison on my DVD player (US)?
Will a Region 1 release ever happen?
