Continuity mistake: When William Petersen is talking to his kid in the supermarket, the cereal boxes behind him on the shelves change between two shots. The items behind Kevin also change during the scene. (01:09:05 - 01:10:20)
Continuity mistake: When Dollarhyde is shot near the end of the film, he falls on the floor of the kitchen and a pool of blood spreads out from underneath him. In the next shot of his body on the floor, the pool of blood has disappeared.
Continuity mistake: In the scene where Graham uses Freddy Lounds to plant a story about the Tooth Fairy in the Tattler, Lounds places a tape recorder on a desk. A few shots later, the recorder is back in Freddy's hand, and he places it on the desk again.
Continuity mistake: After Will has been to see Lecktor, he is standing near a set of traffic lights with Dennis Farina's character. In the next shot a cigarette mysteriously appears in Will's mouth that wasn't there in the previous shot. (00:21:45)
Continuity mistake: In the original theatrical version, Graham shoots six rounds at Dollarhyde from a gun that holds five rounds. [In the Director's Cut, one of the shots has been edited out. However, this is still valid for other prints of the film.]
Continuity mistake: When Graham is reviewing the crime scene in Birmingham, his grip on his tape recorder changes. (00:11:30)
Continuity mistake: When Lektor calls the University of Chicago to get Will Graham's address, the receptionist tells him that it's 3680 Desoto Highway. When Crawford later tells Graham that Lektor released his address to the Tooth Fairy, he says it's 3860 Desoto Highway. (00:32:15 - 01:01:50)
Chosen answer: He wears the stocking over his face for two reasons: (a) to protect his identity (to make Lounds think he'll survive) and (b) remember that Francis believes he is an "ugly monster" so he is also wearing the stocking to defer judgement away from him.
