Continuity mistake: After Lydia cleans off the coffee table when she returns and sits down there are only two boxes and a bowl on the coffee table. When Melanie brings Cathy back from the bathroom there are more than three items, such as an ashtray, on the table and Mitch and Lydia haven't moved from their seats. (01:39:20)????
Continuity mistake: The second shot of the background of the school and the children running down the hill is superimposed behind the five live action children in the front. Watch the boy to the right in the red sweater very closely because in the next shot he doesn't change but the five children in the front do. (01:13:40)????
