Sony’s update of “The karate Kid” bashed all the competition to open this weekend with $56 one thousand thousand marking only about half that was “The A-Team,” proving again that a hit telecasting series from the ‘80s doesn’t always translate to a hit pic This is especially disappointing since the pic took X years to garden truck and was expected the launch a new franchise. “Shrek Forever After,” “Get Him To The Greek” and “Killers” rounded out the top five. Next weekend’s box office should get a major boost from “Toy narrative 3.”
