Martin McDonagh wrote a doozy of a role when he created “Hangmen’s” Mooney, the walking, talking plot device who enters a pub in Northern England, emanating a persona that may just as well be a neon sign that says “stranger danger.” He talks up a storm, does Mooney, and with every word becomes more of a sinister presence in the life of Harry Wade, one of the last hangmen in the UK, and proud of it. In the United States regional premiere of Hangmen by Kinetic Theatre, Mooney is played by the youthful Charlie Kennedy, a recent Point Park graduate. He embodies the cocky-creepy character – although Mooney notes that he prefers “menacing” to creepy.
