Midnight shows are not just for fanboys. Female audiences came out in droves last night for the first showings of highly-anticipated sequel to Sex and the City. The opening take was up 20 percent from 2008’s midnight debut of $2.5 million. That bodes well for a strong showing this weekend against Disney’s Prince of Persia. Should the momentum continue, Sex and the City 2 should surpass the original, which also bowed on Memorial Day weekend to $57 million.
