A few thoughts: A motiveless chase thriller wherein a man gets on the bad side of a crazed trucker who proceeds to stalk him and threaten his life over the course of an afternoon. Shot almost entirely on the road, the two drivers never have a face-to-face moment, which only adds to the disarmingly simple and creepy vibe of the movie. It's weirdly terrifying the way they shoot the truck/trucker, presented as this daunting figure without reason, without a face, and totally relentless in his resolve to torment. Though some of the tension does become defused when they choose to throw in voice-over narration to spell out exactly what the character is thinking and feeling. It's distracting, but never enough to take you out of the story. Although it's a simple thriller on paper, the way it's shot and skillfully choreographed is anything but. Dennis Weaver does a great job in the lead, playing off the situation and nothing else in an appropriately paranoid way. The feature film debut of Steven Spielberg, and one of his greatest and most focused achievements.
Who would I recommend it to? Anyone who enjoys a good Hitchcockian thriller. Watch this if you think Spielberg was just a pop filmmaker -- you might be surprised.
