In the ending scene of the movie with Kate and Adam, they're sitting side by side. They get done talking and she lays her head on his shoulder. His right arm is clearly around her neck, rubbing her head. In the next shot, it cuts to their hands and his right hand reaches to grab her hand. When it cuts back to them with her on his shoulder, his arm has to still be around her neck or else she would have been in an uncomfortable, not to mention different, position. How could his hand be in two places at once?
