As we approached mid-July, according to data compiled by Boxofficemojo.com, the domestic box-office take for films released in 2018 was startlingly top-heavy. According to numbers posted Friday—before the current weekend is factored in—the Top Ten films, led by Black Panther, accounted for $3.34 billion, or 58.8 percent, of the $5.68 billion in sales for 362 movies. So 352 films were left to split $2.34 billion, for an average of about $6.6 million each.
In the year’s second half, of course, performance will even out a bit, as awards contenders and holiday films diminish the lead by first-half blockbusters. But it appears likely that, for the first time in recent memory, the Top Ten films will finish the year with 40 percent or more of the total box-office.
