On Locations Vacations has provided an update on Transformers 4 filming schedule for the Michigan areas. Starting Monday from June 8 to 9th production returns to M-52 outside of Adrian, Michigan to finish filming the scenes they were not able to get a few weeks due to bad weather. Meanwhile in Detroit, filming on the town set at Washington Blvd near Grand Circus Park in downtown Detroit continues with the site being used for filming in early August and prep continues at the Michigan Motion Picture Studio in Pontiac. Potentially added to the filming slate for sometime in the next month or so is the Nicholson terminal on the Detroit river but not confirmed and no specific filming dates.
