One of my favorite movies of all time is Mr. Nobody, starring Jared Leto.
The plot of the movie is complicated, but it is essentially the last mortal man on earth, Nemo Nobody, telling his life story. Nemo tells the story of three stages of his life: at age nine when his parents divorce, at age fifteen when he falls in love, and at age thirty-four as an adult. He then recounts several possible scenarios of his life turned out, without revealing which was the scenario of life he actually lived.
The symbolism in this movie is that life has multiple paths, and every action has a reaction. Without choice, there is nothing that follows. The arrows intertwining represent the paths that Nemo had to choose from, and how they were all intertwined.
