'The Dark Knight' has smashed another record.
First-day Blu-ray sales are in for the box office juggernaut, with Warner reporting that the title moved 600,000 units in the US. Canada and the UK since hitting stores Tuesday.
That easily eclipses the first-day high-def sales of previous record-holder 'Iron Man,' which earlier this year topped out at 250,000 in its first 24 hours on shelves.
'The Dark Knight's Blu-ray take also accounted for 20 percent of total video sales for the title.
"Numbers like these in this economic environment firmly establish Blu-ray as where consumers are headed," Kevin Tsujihara, President of Warner Brothers Home Entertainment, told the New York Times.
Well ahead of the studio's reported internal projections, 'The Dark Knight' is already poised to sell over 1,000,000 Blu-ray copies in its first week in stores.
