Of all the guns-a-blazing, shoot-em-up movie trailers in the history of the cinema, Jay Z’s and Beyonce’s big budget effort is definitely among the most recent. While it’s undeniably star-studded and snazzily-produced, though, it’s really a non-movie trailer (hint: “coming never”), released yesterday to promote their upcoming ‘Run’ tour. But given all the vapors and pearl-clutching that followed other examples of ballistic prop usage, you have to think it’s only a matter of time before the disapproving tut-tuting and tsk-tsking begins in earnest, especially given their recent history of real-life violence. Who will be first to heap opprobrium on Mr. and Mrs. Carter for wanton gun glorification? Shannon? Dan Gross? Josh Sugarmann? The suspense is killing us.
