When Jackie is in the hospital talking on the phone with Ben, she suggests Disneyland (in Anaheim, California) as a place where they can meet in their dreams, to which Ben responds that the last time they went there the lines were too long. This was undoubtedly included in the script by California natives, although both Midwesterners and residents of the east coast, which is where the story takes place, typically take vacations to Disney World in Florida as it is much closer to them.
When Isabel is proposed to on her bed, the ring is slid onto her finger via a piece of thread. Since the diamond on the ring is heavy, it is facing down as it slides toward, and eventually onto her finger. She doesn't adjust this, yet in the next shot it is perfectly facing upward and pushed all the way down on her finger.
Isabel helps Anna get her trees to look real. She paints some leaves on the tree; they are minimal but very big strokes and exceed the sides of the tree. In the next shot, when Anna has a turn, the painting has changed - the "leaves" are tiny and there are suddenly lots of little neat ones rather than the ones Isabel just painted.
When the Thanksgiving pageant kids are waiting for their turns to go on stage and Jackie and Isabel are discussing Anna's love life, Jackie picks up a Bible to hand to a student who is playing Jesse Jackson. In the next cut, however, the student steps up to take his prop and Jackie picks up the Bible again to hand it to him.

Change of camera shot. We see Anna walk in and then the camera goes back to Jackie & Ben. Now the cape has been artfully draped over mother and son. All shoulders are hidden.
On Christmas morning when Isabel is taking the family photo Ben's right hand moves from in front of his stomach to his thigh to under his left elbow. Luke's right hand moves from his son's lap to resting on his shoulder.
Toast is seen automatically popping out of a Dualit toaster with such force that the toast actually leaves the toaster. The Dualit toaster (made in England) does not automatically pop up toast but rather signals that the toast is done with a bell and the toast stays in the toaster keeping warm until raised with a manual lever.
Medical marijuana is not legal in New York, and they actually had lengthy and frequent sentences for possession and distribution of controlled substances until 2001 when Governor George Pataki launched a campaign to reform the drug laws.
At the soccer game, Anna is shown running from behind one of the attacking players from the other team just after the whistle is blown for a kick-off from the centre circle. As defending players must be within their own half for a kick-off and the ball is usually passed backward, this would mean that she was offside before the whistle was blown
