Alan Cumming's one-man "Macbeth" headed to Broadway Alan Cumming is taking his "Macbeth" to Broadway. 15 Photos Stars on Broadway Producers said Friday that the Tony Award-winning Scottish actor will bring his one-man interpretation of "Macbeth" to Broadway's Ethel Barrymore Theatre beginning April 7. In addition to the lead role, Cumming also portays Macduff, Duncan and the three witches from the Shakespeare tragedy. The show will run through June 30. The production, led by directors John Tiffany and Andrew Goldberg, originated at the National Theatre of Scotland and made a stop last summer at the Lincoln Center Festival.
