SUNDAY AM, 4TH UPDATEI think we need the U.S. electoral college to see who’s winning box office this Presidents Weekend. Rival studios are telling me that Universal’s Safe House is edging Sony Pictures/Screen Gems’ The Vow for both the 3-day weekend and the 4-day holiday. (As a Sony exec emailed me Saturday night: I know they’re ahead $400K tonight. We had a $900K lead yesterday. I’d say close but we have good shot to win.”) Either way holdovers are beating all the new films and the North American box office is big. Here’s Top Ten (determined by 3-day weekend numbers):
