TedStixon

Continuity mistake: Throughout much of the third act at the house, the smeared makeup under Kirsty's eyes subtly changes a few times, and even disappears and reappears once or twice. Since she's crying and sweating throughout the sequence, it seems they were reapplying the makeup every so often, and it sometimes didn't quite match. (It happens enough that I think one "blanket mistake" is best, rather than pointing out every single incidence).

TedStixon

Continuity mistake: When Kirsty first encounters Frank wearing her father's skin, Frank says "It's finished" and Kirsty replies "Why is it finished?!" Suddenly, Frank rotates about 90° between cuts. (01:12:30)

TedStixon

Continuity mistake: When Kirsty is fighting Frank in the attic, as she grabs the puzzle box, watch closely. It's very subtle and hard to notice, but the box rotates about 45° between cuts when it punches from the medium shot to the closeup of Kirsty grabbing it.

TedStixon

Continuity mistake: When Frank holds up the puzzle box to show Julia, the box rotates in his hand instantly between edits when it punches in to a closeup. (First, it's the side with the large circle in the center facing out, then it's the side with the much smaller circle facing out.) As the scene cuts back and forth between the two angles, this error keeps occurring. (00:47:18)

TedStixon

Continuity mistake: After Larry stumbles into the attic, he bleeds a pretty large puddle onto the floor. He then stumbles towards Julia, and in the wide high-angle shot, we see no blood on the floor whatsoever, even though it should be visible.

TedStixon

Continuity mistake: When Larry and Julia are checking the house at the beginning, Larry flicks a switch, which illuminates a statue with red lights. In the wide shots where Larry is in front of the statue, the light on him is totally normal and there's also plenty of space to his right. In the medium-profile shots of Larry, he's bathed in red light, and there's a wall only a yard or two to his right.

TedStixon

Continuity mistake: When Frank solves the puzzlebox in the beginning, right before the chains shoot out, there's a wide and then a closeup shot of Frank looking down. In the wide shot, his head is only very slightly tilted down, and he has a somewhat blank look on his face. When it cuts into the closeup, his head is suddenly tilted down a good 45°, and he has a more intense look on his face.

TedStixon

Continuity mistake: The blood smears on Kirsty's shirt change slightly between scenes from when Kirsty is in the attic to when she is walking outside later after fleeing. It's the same shirt and the same day, so it makes no sense why they'd be different.

TedStixon

Continuity mistake: When Kirsty first sees Frank, he grabs the man he's killing and pushes him down to his waist-level. The camera cuts, and suddenly the man is back up and Frank pushes him down to his waist level a second time.

TedStixon

Continuity mistake: After Larry storms away in confusion after Frank skins the rat, Julia's eyes close and her hand moves up to her chest between cuts.

TedStixon

Continuity mistake: When Larry and Julia begin to kiss in their bedroom doorway during the storm, the way they're holding and touching each other changes a few times between cuts. (00:51:28)

TedStixon

Continuity mistake: After Julia sees the vision of Frank being tortured, she walks over to a window and faces it. The scene then cuts to a wideshot, and instantly Julia goes from facing forward, to facing sideways. (00:48:20)

TedStixon

Continuity mistake: When Frank grabs Julia's wrist/hand in the attic after she tells him to "Keep your voice down!," watch closely. The way he's gripping her wrist/hand changes a few times between cuts. Additionally, depending on the angel, her hand either is or isn't casting a shadow on her face. (00:43:36)

TedStixon

Continuity mistake: The shape of Frank's body changes a few times depending on the scene from when he is resurrected to when he absorbs his first "victim." In some shots, it's an extremely skinny body double when it's doing the weird crawling movements, while in other shots where it's the main actor, his body seems a bit "thicker" and "fuller." When it's the skinny body-double, the shape of Frank's head also changes slightly, and is a bit larger and rounder.

TedStixon

Continuity mistake: After Julia kills her first victim, the amount and pattern of the blood on her face changes once or twice over the remainder of the scene. (Most noticeably, it changes from before she drops the hammer, to after when she backs up against the door).

TedStixon

Continuity mistake: After Julia kills her first victim, she drops the hammer and backs away. As the shot cuts, suddenly, a large blood-stain appears on the victim's shirt between cuts. (It's on his shoulder).

TedStixon

Continuity mistake: When Kirsty leaves the bathroom and encounters Julia after Julia first meets Frank, the lighting on Julia noticeably changes between the wide and closeup shots of her. Her shadow on the wall also changes between the two angles.

TedStixon

Continuity mistake: After the dinner scene, Julia goes up to the attic and the shadow she casts on the door changes twice between cuts. We get a POV shot of her approaching the door, and right before it cuts, we see a teeny bit of shadow appear on the door (from Julia approaching it). It then cuts to a wideshot, and there's instantly a LOT more shadow on the door. Then a few seconds later, the shadow on the door changes again during the closeup of her turning the handle - there's suddenly much LESS shadow.

TedStixon

Continuity mistake: When Bill kisses Julia on the cheek as she's about to step away, he puts his hand on her arm, right under her shoulder. When it punches in to a medium shot from the wide, his hand is no longer there.

TedStixon

Continuity mistake: During the dinner scene, when Julia stands up to leave, as it cuts between her and wider shots of the table, the expression on her face and the direction she is facing subtly changes a few times between cuts.
