Continuity: At the beginning, in the scene where Meg decides that she must be the one to go back to get Charles Wallace, her hair is pulled back into a loop bun with only a few hairs loose. In one of the shots in the same scene, it is still a loop bun, but there's a considerable amount of hair that is out, and then in the shot right after that, it's back to being neat with only a few hairs out.
