Continuity mistake: As Mitch checks the window behind the TV set we see the picture of father above the piano there's no shadow on it. Later as they all sit waiting for the bird attack even though no one's turned any lights on or off a dark shadow appears above the middle of the picture. (01:37:05 - 01:40:45)????
Continuity mistake: As Mitch checks the doors and windows look closely at the table to the left of the brown chair on the bottom left of the screen, it has on it an ash tray very close to a plate and a silver box. The shadow of the brown chair falls on the silver box but the next time we see this table, after Lydia straightens up, the brown chair has been moved away to make room for the camera and its shadow no longer falls on the box.
