Where do you see the numbers so early?Box office theory forums. They have two insiders with access to all the numbers pretty much as they come in from all the cinemas. It's usually a poster called Rth who gives his estimate for the day once he's got most of the data. He said 47.8 about 8 hours ago, and Disney official numbers should come in a couple of hours. (Weekend currently looking like 105-110, which beats avengers for 2nd best 2nd weekend)
