Transformers 4 continues to shoot in Chicago, with fans having plenty of access to the set. Four new videos have come in, featuring our first look at Kelsey Grammer as the villainous counter-intelligence agent Harold Attinger. Production is taking place in both the McCormick Place and Millennium Park areas of the Windy City, where several explosions were set off by the crew. Apparently the citizens of Chicago haven't forgotten about the events of Transformers: Dark of the Moon, with many of them carrying picket signs that read, "Remember Chicago!" This anti-robot propaganda is, of course, all part of the movie. In the final video included here, Optimus Prime and a few of the other Autobots can be seen doing their part to make this the best Transformers yet.
