It took heat during the holidays for failing to reach the supremo-blockbuster status that many predicted, but "King Kong" can do some supersized chest-thumping now.

Released as a single DVD and two-disc set on March 28, the Peter Jackson film logged Universal's best first-week sales in studio history, in six days selling 6.5 million copies for a take of more than $100 million.

The previous record-holder was "Meet the Fockers," a studio spokeswoman said.

The film's brisk DVD sales add to its worldwide box-office haul of $550 million. Its ticket sales make "King Kong" the fourth highest-grossing film in Universal's history, following "Jurassic Park," "E.T." and "The Lost World: Jurassic Park."

Universal Pictures is owned by NBC Universal, a joint venture of General Electric Co. and Vivendi Universal.
