Continuity mistake: During the first meal in the new house, the level of Coke in the daughter's glass keeps changing as the camera cuts between her and her mother. The Coke can revolves as well. Sometimes the Coke-logo is visible, at other times the list of ingredients is facing the audience.

Continuity mistake: The girl is inside the room with Forrest Whitaker and the other guy, about the time Whitaker picks up the red thing with the needle, watch the loose hair on the right side of her head, close to her ear: It keeps moving up, down, sometimes is wetter, sometimes dryer.

Continuity mistake: It's raining heavily all night, but when Burnham goes up on the roof to look for a way in, you can no longer hear the rain falling on the window. Later on, we see the rain falling heavily again.

Continuity mistake: Junior's right arm is set on fire, but afterwards, he is stretching his left arm in pain.
Continuity mistake: When Sarah lays down in bed, the towel is still around her head. But a second later, the towel has gone and her hair is dry and brushed.
