Patrick Frater Asia Bureau Chief “Fast & Furious 10” (aka “Fast X”) drove off with the top prize at the South Korean box office on its opening weekend. It earned $4.99 million between Friday and Saturday, according to data from Kobis, the tracking service operated by the Korean Film Council (Kofic). And over its full five-day run, from a Wednesday opening, it earned $6.76 million. Kobis showed the film claiming a 48% market share. The speedy start for “Fast X” was enough to depose “Guardians of the Galaxy 3,” which had ridden atop the Korean chart for the two previous weekends. In its third weekend on release “GOTG 3” earned $3.04 million, a 48% week-on-week decline, giving it a cumulative of $26.9 million after 19 days on release in Korea. That is the fourth highest total for any film that has played in Korean cinemas this year.
