Continuity mistake: When Isabel is helping the daughter make a tree more lifelike, Isabel paints the limbs outside of the round yellow ball shape. In the next scene when the daughter tries to do it, there are no limbs going out of the yellow ball shape. (00:49:30)
Visible crew/equipment: A microphone is visible above the mother when talking to the Doctor about her cancer treatment. (01:37:37)
Other mistake: When Ben surprises Isabel by hiding in the kitchen cabinet, he is in a deeper cabinet, but when Isabel takes him out of the cabinet it is no longer deep enough that Ben could fit inside of it. (00:02:55)
Revealing mistake: The scene where Jackie takes Anna for a night ride in the snow is special for several reasons: Even though it's the first snow of the year and no earlier scene made the impression that it is particularly cold, they come by a lake that's half covered with ice. Both don't wear gloves (horse riders usually wear gloves even in summer!), and, in spite of the cold night, their breath doesn't make any clouds. (01:20:35)
Continuity mistake: When Jackie and Isabel are talking, while Jackie hands out props to the kids for the Thanksgiving play, Jackie removes a book from a shelf and holds it in her hands. When the shot changes, she is seen removing the book from the shelf again.
Continuity mistake: The stone pillars in the middle of the arched windows of Luke's and Isabel's apartment is only visible from outside, not from inside, e.g. in the scene where Isabel helps Anna with her painting. In the scene where Ben calls his mom in hospital there are even two stone pillars. (00:49:35 - 00:53:15)
Continuity mistake: At the end of the movie when it shows a snapshot of the whole family taken with a timer, it ends with a close-up where only Jackie and Isabel are in the frame. The close-up is taken from a different picture because the background is now out of focus.
Continuity mistake: In the breakfast scene at the beginning, two rounds of toast pop out of the toaster very dramatically. But the model of toaster used does not pop, there is a lever clearly visible that is used to manually crank the toast up when the filaments have been turned off. (00:02:45)
