Sony Pictures confirmed to E! News that production on David O. Russell's as-yet untitled political thriller about the 1970s Abscam scandal, which also stars Christian Bale and Robert De Niro, was unaffected.
The cast and crew were shooting today at the federal courthouse and City Hall in Worcester, which is about 40 miles west of Boston.
At this time, the Celtics have a home game against the Indiana Pacers still scheduled for tomorrow and Fleetwood Mac is set to perform at Boston's TD Garden on Thursday.
"The Celtics family sends its thoughts and prayers to the friends and families affected by today's tragedy in Boston. Stay safe," the team tweeted today.

UPDATE: The NBA soon after announced that Tuesday's Celtics-Pacers game had been canceled and no makeup game would be scheduled.
