LOS ANGELES (Variety.com) - The summer 2018 box office is officially ending on a high note. An August surge is thanks partially to “Crazy Rich Asians,” the Warner Bros. romantic comedy that is still doing crazy good business in North America. Jon M. Chu’s film will top the domestic box office for the third week in a row with estimates showing it could make another $27 million to $30 million over Labor Day Weekend.
