Continuity mistake: During Stella and Will's walk, Will's scarf was consistently wrapped one time around his neck, but the length of his scarf on either side varied. The right side was usually much longer than the left side, but the ends were about even other times. When Will was lying in the snow, the scarf ends were almost equal (reaching about half-way down his coat); when he stood up, the ends were far apart. After he fell in the snow, Will got up and adjusted the scarf ends to be about the same in length. (01:25:35 - 01:29:30)
Other mistake: Will got wet saving Stella when she fell through the ice; both were exposed to the bitter cold long enough to suffer hypothermia. Despite their life-threatening ordeal (surely aggravating their chronic condition of cystic fibrosis), each proceeded as if it never happened. Stella immediately went into surgery for a double lung transplant and Will casually hung out in the waiting room. (01:33:27)
