"Heat" has the greatest action scene in cinematic history

Yes it does. At about the halfway mark in Heat is an action scene so astounding that I was literally on the edge of my seat the whole time. In it, a group of four bank thieves are confronted by the police as they attempt to flee the scene, and a bloody, prolonged gunfight drastically changes the course of the rest of the movie (I don’t want to say too much in an effort to keep this relatively spoiler-free).

It’s violent, it’s fast, it’s amazingly edited and very tense, an it feels real (apparently it’s so real that the US Marines use it as an example of the proper way to retreat while under fire). But that’s not why I was on the edge of my seat. I was on the edge of my seat because of the writing! The movie makes painfully clear what’s at stake for every character who has a part in the scene.

Robert De Niro’s character Neil and Tom Sizemore’s Michael are there because they are thieves and it’s the only thing they know how to do, the only work they can really take pleasure in. (One interesting aspect of this movie is the links it makes between cops and robbers, two classes of professionals who work on opposite sides in the same field, often using the same methods.) Neil agreed to do the job for Val Kilmer’s character Chris, who is there because he’s a gambling addict and thinks that the money will help him out of his debts. He also wants the money because he sees it as key in saving his disintegrating marriage (it’s not, the viewer is aware). Donald, played by Dennis Haysbert, is a getaway driver called in at the last minute. He’s an ex-con, trapped in a miserable job assigned by his parole officer, who gets back into the game because he’s sick of being treated like shit by the real world he tried desperately to join. Finally there’s Vincent, played by Al Pacino, the cop who has become obsessed with the head thief, Neil. In Neil, Vincent sees a reflection of himself, a professional torn by the complications of the career he chose.

For the first eighty minutes of the movie we’ve seen these characters fight with their wives, love their children, go out for drinks with their families and friends, and argue whether or not hitting the bank is worth the risk. We’ve seen Neil meet a woman named Eady who asks him if he’s lonely. “I’m alone, I’m not lonely,” he replies, but his relationship with her and his friends reveals that he’s desperately alone, trapped in his work, and unable to make a real connection with anybody. More so than in any crime movie—maybe with the exception of The Godfather—you feel like you know these characters. They’re not just cops and robbers, they’re people, they’re practically your friends, which is why, when Chris sees Vincent across the street and raises his gun to fire, I panicked. I don’t want any of them to die! I thought.

You have to see this movie. It’s awesome, and it’s surprisingly well-written for a Hollywood crime thriller—there are a few clunkers, but for the most part the characters express themselves with cliché-free eloquence—and the gunfight is only one of several amazing scenes. Here's a link to a YouTube video version, but you really need to see the whole movie to get the full context.
