Dropping hints during a radio interview with WGN Chicago, director Michael Bay stated that they will be returning to Chicago for the principal photography of Transformers 5.
As of now, the scale of the shooting is not mentioned. Chicago may have a Transformers: Dark Of The Moon scale of shooting or may double for another location like Transformers: Age Of Extinction.
Mr. Bay was also critical about production companies wanting to do big budget franchises instead of stories like 13 Hours: The Secret Soldiers of Benghazi which is currently a commercial and a critical success.
2005 Boards Member Jimmy88 brings us this news and is eagerly waiting to update us from Chicago, much like his massive coverage during Transformers 3.
