'Matrix' sequel opening off 45 percent
LOS ANGELES -- The sci-fi Matrix saga lost some of its spin at the U.S. box office, with "The Matrix Revolutions" pulling in $50.16 million in its opening weekend -- off 45 percent from the previous chapter's weekend debut. "Revolutions," pummeled by critics as harshly as "The Matrix Reloaded" was last May, has grossed $85.5 million domestically since debuting Wednesday, according to studio estimates Sunday.
