Continuity mistake: Between shots from when Vilmer leaves the kitchen (and throws the big broken part of door at the wall) and then when W.E leaves the kitchen seconds later, the trash over the hallway floor and the kitchen floor (cardboard, wood, paper) drastically differs position and location, and additional trash appears too.
