By 1990, the cost of the average U.S. film had passed $25 million. Of the nine films released that year to gross more than $100 million at the U.S. box office, two would have been strictly B-movie material before the late 1970s: "Teenage Mutant Ninja Turtles" and "Dick Tracy". Three more—the science-fiction thriller "Total Recall", the action-filled detective thriller "Die Hard 2", and the year's biggest hit, the slapstick kiddie comedy "Home Alone"—were also far closer to the traditional arena of the B's than to classic A-list subject matter. The growing popularity of home video and access to unedited movies on cable and satellite television along with real estate pressures were making survival more difficult for the sort of small- or non-chain theaters that were the primary home of independently produced genre films. Drive-in screens were rapidly disappearing from the American landscape: between 1987 and 1990, the number in operation fell from 2,507 to 910.
