I thought you might be interested to read this review of the new Region 2 Special edition DVD of CITIZEN KANE which is not actually released until the end of July in the UK.
Frankly, I thought the Warners release was magnificent, barring the odd raindrop going AWOL, but this review is nothing short of a rave - I wished they'd licensed the BBC doc on the Making of Kane as that is by far the single best documentary on the film (and MUCH more impressive than the overrated BATTLE OVER CITIZEN KANE which seems weirdly biased towards Hearst - or maybe that isn't weird - it's certainly unconvicning though).
