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: The hole in the Shell Beach poster is a different shape when Murdoch tears it than after he punches through the brick wall behind it - the poster runs right up to the hole. (01:15:30)
Continuity mistake: When Mr. Hand pricks Emma's throat, the blood moves from the middle of her neck to just under her jawbone and changes shape between the closeup and the larger shot. (01:17:25)
Continuity mistake: When John is in front of the shop window trying to remember his first name, there is a small sign in the window saying "Back at 3 o'clock." A few shots later when John starts spinning in a circle, the sign is backwards, revealing a flipped shot.
Continuity mistake: When John falls down after reading the newspaper clippings in front of the Shell Beach billboard, one of the Strangers can be seen approaching him on the far left of the screen, in front of a window at the top of some stairs. But in the next shot, the Stranger is suddenly further down the stairs.
Continuity mistake: When John is visited in jail by Emma, he is escorted by one policeman. A second policeman then magically appears in the close-up.
