has begun filming in Downtown Cleveland this morning. Nearly six city blocks are closed off surrounding the intersection of East 6th and Rockwell.First thing on the docket was a close-up of a crash scene involving a black (possible S.H.I.E.L.D.) government SUV and a Washington D.C. police car. The cop car was smashing into the driver's side door of the SUV while both vehicles were on rails to control the speed of the impact. Most likely, this was the extreme close up work of the cameras capturing the actual impact of the two.Nick Fury's stunt double was also spotted on the scene. Check out the location photos below.More to come from Cleveland as The Daily SuperHero is your on-site source forfilming over the next month-plus.
