Philly​.com have pointed out that the Trans­form­ers II pro­duc­tion team will very soon be start­ing their work in and around Philadelphia,

Keep an eye out for Shia LaBeouf, Josh Duhamel, Megan Fox and John Tur­turro over the next two weeks as Michael Bay puts Trans­form­ers 2: Revenge of the Fallen before the cam­eras in Philly, start­ing tomor­row. Among loca­tions: Peco [Philadel­phia Elec­tric Com­pany] plants along the Delaware, the Uni­ver­sity of Penn­syl­va­nia (because LaBeouf plays a col­lege stu­dent), and East­ern State Pen­i­ten­tiary. Last week’s shoot­ing in Beth­le­hem, Pa., was a blast, as the old U.S. Steel plant hosted explo­sions and whirring Black Hawk helicopters.
