Continuity mistake: Malloy places his flashlight on the floor about a foot and a half away from the door and at an angle. When he opens the door, the flashlight is now right up against the door and directly perpendicular to it.
Continuity mistake: A brick being shoved into place attracts Malloy's attention. The mortar is not neat and tidy, wet, and the bricks are slightly askew. When Malloy turns to face the brick wall, the mortar is neat, dry, and the bricks neatly laid.
