Continuity mistake: When it shows Mandy reading from her book, she has nothing visible sticking up from it in the wide angle. When it cuts to a close up suddenly the dollar bill she's using as a bookmark appears. It's first on the right side, then switches to the left side and further down. (00:17:30)
Continuity mistake: The Stalker, "Shrike," is a persistent hunter, but not terribly quick on his feet. He's sort of a lurching, Frankenstein-like cyborg who is always pursuing Hester Shaw at about walking speed. When Valentine frees Shrike from Sharkmoor prison, miles out to sea, we see Valentine in his airship destroying the prison and we see Shrike's prison cell sink to the sea floor. This cuts to a long distance shot of the prison exploding and sinking in the far background, miles away, as Valentine's airship comes sweeping from the far background into the foreground and out of frame. Almost immediately, Shrike emerges from the surf in the foreground and slowly trudges ashore, implying that he somehow travelled miles across the sea floor just as swiftly as did the airship, in a matter of moments, despite his slow, lumbering gait.

Continuity mistake: In Alice's apartment the clock on the wall has the time as 8:40 when she is standing and kissing David. They have sex and Veronica comes over. Alice and Veronica talk and the clock still shows 8:40. (01:20:00)
Continuity mistake: When Riley's boss says he's giving her extra hours and she's closing, Riley looks down to the side in her close up. When the camera cuts again as he walks away, she's suddenly looking up straight ahead towards him as he walks. (00:08:40)
Continuity mistake: When Nick Cage and the woman get to her place and start to make out, he takes her bra off, leaving her bare chested as he fondles her. It cuts to a different angle as they are kissing and suddenly her bra is back on again, only to be gone in the following shot.
Continuity mistake: Constance is hugging Mary. In the close up shot, Constance is wearing a round sky blue earring. In the long shot, the earring is not seen even though her ear is fully facing the camera. (00:27:45)
