24 April 2008 Dune (1984) on Blu-ray (in France)
On 10 April 2008 Opening released David Lynch's Dune on Blu-ray. The extras are the same as the Dune: Ultimate Edition DVD released in France 3 years ago, apart from the short sound restoration segement is missing.
The French 'Ultimate Edition' DVD is considered to have the best transfer of all the Dune DVDs released, so hopefully this 1080p transfer will look even better!
