Joel Schumacher's minor, but tightly constructed high-concept thriller Phone Booth clocks in at a brisk and efficient 80 minutes that transpires onscreen in real time. At heart a highly charged B-movie, the film would be easy to dismiss if not for the flashes of smart dialogue and the solid lead performance of Colin Farrell. Given only a few minutes to establish his character before being plunged into a life-threatening situation, Farrell communicates Stu Shepard's remarkable facility for sleaze in both his personal and professional life. His unlikability brings the film its enjoyable buzz. As the disembodied voice of the caller (expertly performed by Kiefer Sutherland) terrorizes him, Stu's questionable morality allows the audience to side with both the cat and the mouse throughout the ordeal. That Farrell actually succeeds entirely in winning the viewer's sympathy is a testament to both his skill and the unrelenting tension of the direction and screenplay. An enjoyable popcorn film, Phone Booth delivers the goods in a neat and tidy package.
