The Dark Knight is a Blu-ray Disc superhero, selling a record 600,000 copies on the new format 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.

The studio believes U.S. Blu-ray sales could hit 1 million high-def copies in week one—a format milestone—according to WHV president Ron Sanders.

“We think we will hit 1 million this weekend,” said 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.”
