I was watching Age of Adeline tonight and thought of a scene from a similar movie. There is a scene in the movie where the ballet (?) dancer walks out into the street and possibly bumps into someone or gets in an accident and that action create a ripple effect. That one action ends up affecting a lot of people and their lives due to the ripple effect. I believe the scene is set maybe in the 1940s or 1950s, but the movie itself is fairly new.
