I work in the General Motors Tech Center in Warren, Michigan, which is where a lot of the cooperation with the Bay Transformers movies comes from. We also have a weekly newsletter in the Tech Center. The cover story this week was about the work several of my co-workers did on the film, particularly on Bumblebee and the Stingray character. Also, several scenes for Age of Extinction were filmed on GM grounds here in Warren and in other parts of Michigan. Here are scans of the article, and a recording of it being read. https://www.youtube.com/watch?v=EsB4h2Ny1s0 Also attaching a picture of the Tech Center design building lobby.
