Continuity mistake: When the family goes to throw Carla through the window, watch the window they throw her towards. The window is made up of at least three sections of glass, each no more than 2-3 feet wide with metal posts between sections.

When the shot changes to outside, that post, which should now be farthest to the left, has vanished.
