Continuity mistake: After Chris is dead, and his wife is writing in her diary, and she writes "I still exist" as she's writing it, exist is written "EXST", then when she looks to read what she wrote it reads "EXT". The writing's different too. (00:22:10)

Continuity mistake: In the scene where Murdock is in jail talking with Emma on the phones through the glass, he presses his fingers to hers, against the glass, & the glass shatters. Right when it is shattering & he pulls away, if you look very carefully you can see the reflection of his hand in an additional pane of glass that is still there! The next shot shows no glass as they kiss, but when the original glass breaks, there is still a pane of glass remaining, as evidenced by the reflection of his hand. (01:05:08)
Visible crew/equipment: When the Nihilists are ordering food at the restaurant, you can see the reflection of the camera and cameraman in the window behind them.
