In most of these Weekend Box Office Reports, it’s clear who the victor will be. Even when the early estimates are a little off and the numbers shift between now and Monday, the basic layout of the top 10 is generally pretty accurate. But this week is a real race and the top two films are neck and neck, and we won’t know who will actually win this thing until tomorrow. But right now, early estimates have Melissa McCarthy’s new comedy The Boss barely edging out Batman v Superman: Dawn of Justice by less than $50,000. That’s crazy and, whether it actually claims the top spot tomorrow or not, very bad for Batman v Superman.
