Fifteen people were injured when the MBTA bus careened into a truck loaded with camera equipment on July 9 morning, reported Boston Chronicle.
Deborah Simmrin, unit publicist for "The Heat", said the stars of the film Bullock and Melissa McCarthy were in a building across the street when the crash occurred.
Simmrin said that the driver of the truck suffered minor injuries but returned to work after the accident. She said the crew had not checked to see if any equipment was damaged.
"We just continued working," she said.
Directed by Paul Feig, the film is about an FBI agent who teams with a local police officer to nab a Russian mobster.
Earlier, Bullock made a big-budget flick in the Bay State, "The Proposal" with Ryan Reynolds where she and her then-husband Jesse James were hit by a drunk driver while picking up a birthday cake for their dog in Gloucester.
