Anyways thats not why i have your attention its what happened during filming
Then, on October 11, while filming a chase scene at 3rd Street and Maryland Avenue, SW, a Washington DC Metropolitan Police K9 Unit SUV struck the car that portrays Bumblebee in the film. The area had been closed off by the DC police, and it isn't clear why the SUV got in it. Both drivers were uninjured, [29][30] but the car was severely damaged.[31]
And for added bonus
Filming was temporarily delayed on September 2, 2010 in Hammond, Indiana, when an extra was seriously injured during a stunt.[23] The extra, identified as Gabriella Cedillo, had to undergo brain surgery after her car was struck by a flying metal object. Cedillo was not part of the stunt crew and she was 500 feet away from the stunt scene.[24] The injury has left her permanently brain-damaged, paralyzed on her left side and her left eye stitched shut.[25] [26] As a result, Paramount took responsibility por the accident and decided to cover all medical costs incurred by Cedillo.[27] In spite of this, on October 5, Cedillo's family filed a lawsuit, which cites seven counts of negligence against Paramount, D.W. Studios and several other defendants (not including Bay), with total damages sought in excess of US$350,000.[28]
