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)
Continuity mistake: Murdoch has to break in a window to escape from being crushed by a building. The first scene shows him kicking in the window with many jagged pieces at the top of the window frame. Another scene then shows Murdoch still removing the glass, but now there are only two smooth fragments at the top of the window. We then see Murdoch moving his head through the window and entering into a room with no glass at the top of the window frame. All the while, during those three quick scenes, there was no effort by Murdoch to clear the broken glass at the top of the window. (00:59:25)
