J. Kim Murphy Audiences don’t seem to intend to attend the latest “Expendables.” The fourth entry in the ensemble action franchise is notching a series-low opening day from 3,518 theaters with about $3 million, a figure that includes a meagre $750,000 in Thursday previews. Produced by Millennium Media and released by Lionsgate, “Expend4bles” is projecting a debut that’ll fall well short of the $15 million to $17 million range that had been expected heading into the weekend, and also behind the $15.8 million sum that “The Expendables 3” put up nine years ago.
