During the trial scene, Martha's hair is pulled into a ponytail. When she exits the courtroom during the break, her hair is loose. When she enters the shop to develop the photo of her daughter, she has a ponytail again.
The painting in the lawyer's room, which her partner referred to as Tacoma Bridge, is actually Bosphorous Bridge in Istanbul, Turkey, with Ortaköy Mosque in the foreground.
The film takes place in Boston, where trees do not have full leaves until well into May. In the courtroom scene labeled March 22, Martha wears a winter coat and there are small bits of snow on the ground outside the courthouse, typical for that time of year, yet trees are shown with full green foliage. When Martha leaves the courthouse during a break, the trees appear to be bare with some snow on the ground. The trees are full again in the scene on April 3, still several weeks before they would be in Boston.
Martha's family are supposed to be Jewish (see the Hebrew on Yvette's gravestone). Cremation is not a Jewish practice, yet Martha pours Yvette's ashes into the river in the closing scene.
Sean uses a 35mm camera to photograph the new baby after he fetches a perfectly serviceable smartphone camera from the bathroom.
When Sean sees a painting on the wall of Suzanne's office, he claims that it's the Tacoma Bridge. It is actually a painting of the Bosphorus Bridge, which is in Istanbul, Turkey. It can be easily distinguished by the mosque next to it.
