Ben Affleck on "The Town" movie set
in Boston last weekend.
Ben Affleck is expected to bring a film crew to Somerville Hospital this weekend to shoot scenes for his upcoming movie "The Town," according to a source close to the hospital.
"It could be both days," he said, adding that the hospital would likely finalize an agreement with the production company on Tuesday.
He said Affleck, who grew up in Cambridge, and his team would film somewhere on either the second or third floor, and the rest of the hospital would remain open during the shoot. It's likely Affleck's arrival will cause a stir, and draw a crowd, though they won't get to see much.
"If people come they'll have to stand along the street," the source said, adding that fans will be barred from entering the hospital. "They won't be able to see anything."
The news surprised a front desk worker on Tuesday, who quipped, "I'll come in [to the shoot] as an injured patient."
Hospital staffers have placed signs on the bulletin boards on the upper floors - which housed the hospital's in-patient treatment facility, until it closed in July - to make the wing appear operational, the source said.
