The Dorchester native was seen in Boston police gear on Boylston Street. Last month he posed in uniform with the Quincy Police Department after filming scenes with a SWAT team.

Patriots’ Day chronicles the story of the 2013 Boston Marathon bombings. Wahlberg will star as a police officer who is central to the investigation, and the subsequent manhunt that shut down the city.

The actor previously said that he feels “huge pressure to get this right,” and is committed to the project.
