The Hollywood veteran is set to star in a biopic of Benjamin Franklin, currently being filmed in France.
He was spotted in full Benjamin costume, wowing onlookers with his uncanny resemblance to the late philosopher.
Michael has also grown out his curly locks to match the part, opting out of his signature-styled silver bellows.
Bundled up in historically accurate winter gear on a chilly day, Michael was joined by his costar Noah Jupe on the banks of the river Seine.
The new series was announced by Apple TV+ in February but an official release date is yet to be set.
