Look at him, he's pretty nice looking...right? Just trying to make his way in this uncertain world like all of us. He's a nice guy, except when he's a sociopath.
Jake Gyllenhaal changed everything about himself for this role; his stare, his posture, his grin, and even his matter of speaking. Nightcrawler is the film that proves that Gyllenhaal is a worthy actor who has finally found himself. Lou Bloom at no point in the movie appears innocent, however you can find a way to relate to him. In the beginning of the film, he's just trying to find his way, and find a job that will benefit his future. He gets turned down a couple times, but then find that there's a business opportunity in which to employ himself. So Bloom becomes a nightcrawler: someone who gathers footage of crime scenes to sell to the local news.
While the concept of a movie in 2014 focusing on the local news seems dated, it seemed pretty perfect for Gyllenhaal's character. He is a man that walks around when everyone is asleep, attempting to get to crime scenes before the police even get there. The reason this is perfect for portraying Bloom's sociopathic tendencies is due to his unflinching ability to film a dead body, see someone bloody and hurt and objectively look at the situation. He does not help people because he does not care about people, he needs them to be hurt or dead in order to get his business off the ground. A bloody body is just another sale.
You'll watch this movie having no idea what Lou Bloom is capable of. You know he's not a great dude, but you have no real idea how far he'll go for success. The movie develops our view of him; we know he's horrible, but we don't fully learn how horrible until we make our way further through the film. It's all very philosophical, and you may be disturbed by how much you can relate to this character. (Or maybe you can't relate)
Nightcrawler is extremely creepy, thrilling, and suspenseful. If I were to pick my favorite movie since the end of summer it would be a close match between Nightcrawler and the similarly-toned Gone Girl. It's definitely one-of-a-kind, and something that Jake Gyllenhaal will be remembered for.
