The Avengers movie kicked off filming with a bang Monday amid explosions in downtown Cleveland, as East Ninth Street was rocked with pyrotechnics designed to simulate an attack on 42nd Street in Manhattan. Chris Evans arrived on the set, basking in the success of Captain America. Fellow cast members Samuel Jackson and Jeremy Renner had been in Plum Brook near Sandusky last week to shoot scenes in a NASA facility. Watch video footage of Monday’s explosions below.
