Movie: Jaws (1975)
If you haven't heard of this movie, you must have been living under a rock your entire life. Most people can easily hum the Jaws attack tune, or can recognize the "We're gonna need a bigger boat" line as being from Jaws. But surprisingly, there are a lot of modern horror fans who have not actually watched the movie. This is nothing short of a tragedy, as the film is a classic in every sense of the word.
I think most people would agree that sharks are pretty darned scary. Would you want to meet one while you're out boogie-boarding? Jaws capitalizes on this fear perfectly with a huge, imposing shark brought to life with some mighty convincing effects. It also displays the ease with which a shark could actually wreak havoc at a beach. And therein lies the true horror of Jaws. This could happen. This could really freaking happen. To you.
Scares aside, the characters are great. I had a certain love for Hooper and Quint, who were both incredibly well written and acted. Quint in particular just exhumed awesome from every pore in his body. He's a badass professional shark hunter. How can he not be awesome? The onscreen camaraderie between Hooper, Quint, and Brody is really what makes the film.
There are three sequels. Jaws 2 is basically a continuation of the first film and is definitely worth checking out. Jaws 3 gets a little sillier but is still a lot of fun. Jaws 4 (called Jaws: The Revenge) has a silly premise but is worth watching for the lovely scenery and the fact that the protagonist is a pretty cool middle-aged woman (rare!).
All four Jaws films are available on DVD.
