Interesting Review

Of A Scanner Darkly, the movie based on a Phillip K. Dick story. Quote:

Like Dick’s book, the film unfolds with anarchic fitfulness. Arctor (a vacant, melancholy Keanu Reeves) is narcotics agent who works undercover as a dealer of Substance D, a street drug that has the unfortunate side effect of splitting its user’s hemispheres into separately functioning parts, each unaware of the other’s existence. Problematically, Arctor’s primary target of investigation is himself, meaning that much of the movie consists of watching a scramble-suited Arctor watch surveillance tapes of himself and his tweaked-out druggie pals, Barris and Luckman. Played by Robert Downey, Jr. and Woody Harrelson, Barris and Luckman are druggie’s druggies — twitchy, fried minds that alternate between conspiratorial theorizing and dim-bulb buffoonery. Downey and Harrelson, two well-known real-life heads, give these scenes both a jittery comedic flavor and a buzz of authenticity. Take note: This is your brain on drugs.
