Scene from the Film

The scene from the film Philadelphia that stood out the most to me was when Andrew Beckett was with his family for their parents wedding anniversary. The home video/camera stops on his mom for a while and we see her face change from a smile, to one of deep concern a minute after hugging Andrew. I think this scene is a  very clear example of pathos because its another example where the film tries to tell you that something is going to happen to Andrew or at least something is wrong. The viewer is made to feel deep concern for Andrew and his family.I think its interesting that the film chooses things that Andrew especially misses, would we have ordinarily noticed this slight and late change in emotion?
