“A Scanner Darkly” is one of those movies where nothing is as it seems, and the viewer’s perception of what’s really happening changes several times throughout the film. This feeling is enhanced by the animation technique, in which the director filmed a regular live-action movie, and then drew over the top of it and animated the drawings. This results in the main characters, played by Keanu Reeves, Winona Ryder, Robert Downey, Jr. and Woody Harrelson, being completely recognizable in their animated forms, right down to their most subtle facial expressions. “A Scanner Darkly” examines the negative effects of drug abuse, by creating a futuristic world in which 20 percent of the population is addicted to a drug called Substance D. The movie depicts the lives of a small group of addicts, and contains a lot of drug use and references, and also some sexually explicit material. Ultimately, the film does a good job showing the catastrophic effects drugs have on the human mind and body; however, due to the explicit material and language, “A Scanner Darkly” cannot be approved by Dove.
