LOS ANGELES (AP) - "Gravity" again is holding it down at the box office. The movie starring Sandra Bullock and George Clooney continues to dominate ticket sales, taking in $44.3 million over the weekend. That's only a 21-percent drop from last weekend's take. Usually a film will bleed off about half its revenue from opening week to the next. Number two is "Captain Phillips," with $26 million of box office business. Meanwhile the second installation of "Cloudy with a Chance of Meatballs" grabbed third place. Its followed by the weekend's other new release, "Machete Kills," which took in $3.8 million dollars.
