When the time comes to re-create the explosions that killed three people and injured more than 260 others at the finish line of the 2013 Boston Marathon, the cast and crew of the movie “Patriots Day” will be far away from the site of the tragedy. Director Peter Berg plans to film the deadly scene on a runway at the former South Weymouth Naval Air Station, where workers are busy building a stand-in for the Boylston Street blocks where the bombs went off. Friday, a crew from the movie was working on the set, which is a series of storefronts similar to those on Boylston Street near Copley Square. The movie, which stars Mark Wahlberg as a Boston police officer, John Goodman as former Police Commissioner Ed Davis, and Oscar winner J.K. Simmons as Watertown Police Sergeant Jeffrey Pugliese, has already filmed scenes in Dorchester and Quincy and is scheduled to film on the MIT campus, in Watertown, and elsewhere in Boston. (The scene depicting the gun battle with the Tsarnaevs will not be shot in Watertown.) “Patriots Day” isn’t the only movie shooting at the South Weymouth Naval Air Station. “Stronger,” starring Jake Gyllenhaal as bombing survivor Jeff Bauman, is also filming scenes there.
