Alpha23

Visible crew/equipment: In the scene where the staff member is cleaning up the research room with the animal cadavers there's a top-down shot of him at the communication panel. Directly in front of him there's a microphone visible that seems to be held by a filming crew member, as it moves out of sight after some seconds. (00:15:35)

Plot hole: The very last scene shows Mary building a wall, apparently in her belfry. But there should still be the original wall that Rose built, with the hole in it that Mary smashed in. By killing Rose / having killed Rose, she prevents further harm, but all effects that took place before that (also the building of the wall), should stay (like her scars). It is very unlikely Mary broke down the whole wall just to add another body. (01:28:25)

Alpha23

Continuity mistake: When The Spirit is hit by the severed head in the first fight, you can see that the projectile thrown at him doesn't look like a head at all. However, it changes back when he is hit. (00:10:55)

Alpha23

Continuity mistake: When Jamie surfaces on his escape from the theater, the flashlight he was carrying disappears between shots.
