What goes up must come down—but it hasn't happened yet for highly lauded 3D thriller Gravity, which topped the box office for a second weekend with $44.3 million in ticket sales. Tom Hanks-led Somali pirate flick Captain Phillips sailed in to No. 2, grossing a seaworthy $26 million in its debut weekend, the LA Times reports. But it was a far less successful maiden voyage for Machete 2, which flopped with only $3.8 million, putting it at No. 4. It was bested by Cloudy With a Chance of Meatballs 2, which scored $14.2 million in its third weekend, per the Hollywood Reporter. And coming in at No. 5, Runner Runner and Prisoners tied with $3.7 million apiece.
