I recently purchased The Battle of Britain (1969) on DVD.
Second hand from a antique store in Wanganui.
$4.
I remember my dad taking my brother and I to the movies to see it in the early '70s.
Last Saturday I cranked the volume up on the home theatre and watched it on a projector.
Awesome!
The Hurricane does not feature much but I don't think you make such a film again without significant use of CGI as these aircraft are so rare now.
From memory Churchill's quote was something like: Never in the field of human conflict has so much been owed by so many to so few.
On another note I did read today that the last surviving member of the Dam Busters squadron passed away today. Les Munro was aged 95.
