A herd of sheep. Three sheepdogs. And five human actors. All converged on the Green June 29 for the public debut of Doggie Hamlet, a performance loosely based on the novel, The Story of Edgar Sawtelle, which is loosely based on Shakespeare’s Hamlet. Created, choreographed and directed by dancer Ann Carlson, the Hopkins Center-sponsored show featured a mix of improvised movement and dance, some yelling at and chasing of sheep, and minimal dialogue.
