Continuity mistake: Near the beginning, when Joy sees the IQ game, the two poles are close together and there is nothing directly beside it. But when she gets close and the camera changes angles the poles are now separated and a small gold toy is sitting beside it. Then when she leans down next to it the poles are still separated, but the toy is gone. (00:00:40)
Continuity mistake: When Carl is staying with the son Earl in his motel room after he separated from his wife and starts going back and forth for the room, there are two socks on the floor by the bed, one of which changes position in another shot.
Continuity mistake: When Earl's mother is in the bathroom stall we see she has a tiny bit of toilet paper on the roll next to her. As Joy puts her head underneath the stall the amount of toilet paper is now much longer than before. It goes from half a square of paper to about 2-3 squares of paper.
