Disney’s “Pirates of the Caribbean: Dead Man’s Chest” reaped a bounty at videostores its first week, outpacing all other bows for the year with 10.5 million units sold.

The debut easily topped that of the year’s previous record holder, “Harry Potter and the Goblet of Fire,” which sold nearly 9 million discs the week of its March bow, but falls slightly short of the 11 million units of the original “Pirates” sold in its first week on shelves in December 2003.
