Performed in deep, intimate tones by Wilkerson, with home movies and his grandfather’s favorite rocking chair haunting the stage, Did You Wonder Who Fired the Gun? is a radical new iteration of a “live documentary” that is part séance, part detective story, part horror story, and 100 percent American story. As the narrative unfolds, the discomfort becomes electric, and there is a feeling of real risk that spirits will be raised from the dead. What will the storyteller do? Will he sit in that chair? Will he own up to it?
