The makers of the upcoming film about the Boston Marathon bombings are preparing for their biggest day of shooting.
The 2013 bombings will reportedly be recreated in Weymouth, Massachusetts, over the next few days.
A replica finish line was constructed on an old runway and replica store fronts have been erected.
"Patriots Day" stars Boston native Mark Wahlberg.
The movie is reportedly slated to open in limited release in December and nationwide in January 2017.
