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 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: At the part when Mr. Sleep scratches his knife against the wall and Murdoch falls out of the doorway. The door is on the right side, but when they show the downward shot, it is on the other side. (01:00:00)
Continuity mistake: Emma steps in front of John to protect him from Bumstead at their apartment and says, "You have the wrong man." But in the previous shot and the next one, she is about two feet farther to John's left. (00:23:35)
Revealing mistake: When John looks at the newspaper clippings allegedly about the serial killer, you can see that the body of the articles is nothing whatsoever to do with serial killers and murders, irrespective of the headlines. One is from WWII, about the Japanese army being bombed. The others similarly are unrelated to the murders. (00:20:12)
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.
