I just checked on Wrath of the Titans, a Warner Brothers film whose domestic theater pattern DS has been similar to, and tomorrow it will be beginning its 12th and quite possibly final week in theaters. And the reason it could be its last week is because, if they haven't already done so, studios often tend to pull films out of theaters by the Thursday before their DVD/Blu-ray releases - and the Wrath of the Titans' DVD/Blu-ray comes out June 26th.
So, IF DS was to similarly stay in theaters for 12 weeks and then release its DVD/Blu-ray, which of course is not a given, but if, then its DVD/Blu-ray would not be coming out until August 7th. However, DS has not followed Wrath of the Titans' foreign release pattern in that DS didn't open in Latin and South America at the same time that it basically did in Europe, Asia and Africa, and Australia and New Zealand. DS doesn't begin to open in Latin and South America until June 22nd. And video piracy being what it is these days, Warner Brothers may hold off releasing DS on DVD/Blu-ray until after the film has run its course in Latin and South America - and who knows when that will be?
34 days 16 hours 34 minutes 50 seconds since the Depp/Burton Dark Shadows has been in release(ET)!!
