For what it’s worth, the Hollywood Stock Exchange forum has posted MTC (Major Theatre Chain) tracking figures and they’re forecasting a $28 million opening for The Social Network (Sony, 10.1). MTC numbers “come from some mysterious source within a major theater chain,” I’m told, “and are usually pretty accurate.” So yesterday’s projection of $26 million from was within the same estimated realm. The figures will be honed on Wednesday and Thursday once everyone factors in online ticket sales and yaddah-yaddah.
