The Dark Knight sold a record 600,000 Blu-ray Discs in the U.S. on its first day of release on Dec. 9, or about 21% of its total units, according to Warner Home Video.
"We think we will hit 1 million this weekend," said WHV president Ron Sanders. "What's really encouraging about it is that the Blu-ray version did exceptionally well across the board. It wasn't just selling in Best Buy or Wal-Mart, but also it did well in grocery and game stores. It was surprising to us just how well it did."
Prior to The Dark Knight, the best Blu-ray Disc performer was Paramount Home Entertainment's Iron Man, which moved 260,000 high-def copies on its first day on sale Sept. 30, and 500,000 units in its first week.
This year's highest-grossing film, The Dark Knight, which generated $530 million in U.S. theatrical ticket sales, moved about 3 million copies in both standard and high-def in the U.S. on its first day of release.
The movie's 21% Blu-ray Disc share of sales easily tops the average 10% portion that was generated from releases in the format earlier this year.
