As mentally-challenged Lenny in the Stageworks version of John Steinbeck’s Of Mice and Men, Duggan was convincing to the point of miracle. From the infantile way Duggan spoke to his friend George, to the worry lines on his bewildered face as he sought sense in a confusing world, this was precisely the innocent but lethal simpleton from 1930s California that Steinbeck conceived, dangerous to small animals and to women who treated him tenderly. Acting this good is uncanny.
