Walker is a series of video essays that document contemporary architectures. Each film is based on improvised shots by two cameramen walking through a specific construction, using only one camera. As they progress, the walkers exchange the camera, observing and filming the space around them and each other. Rather than an exhaustive description of a specific site, the films show the relationship between the observers and their subject: as the two filmmakers recreate the space before them, the space affects them and turns them into fictional versions of themselves.
