I love this shot because, after an hour or so of (mostly) fun and games as Graysmith pursues his passion, we're reminded right at the end of the tragedy and horror of the killing spree. This young man just looks destroyed, even after all the years since.
Great point. Zodiac is one of the most horrifying and scary movies I've seen, since it happened
. It was for real.
Also, I love that not only is the last character we see in the movie also the first character we see, but that they bring back "The Hurdy Gurdy Man" on the soundtrack just at the end. Just as the character remembers that night, as he remembers the song. I was in a theater with three other people but when the credits rolled I fucking stood up and applauded. I was so impressed by the movie.
