Alan Cumming takes on a multiple-personality 'Macbeth'
It's easy to forget that Alan Cumming is Scottish, given his facility with accents and extensive work in the U.S., including his supporting role in CBS' "The Good Wife." This summer, Cumming is starring in the mother of all Scottish plays -- Shakespeare's "Macbeth," in a production by the National Theatre of Scotland that is currently running at New York's Lincoln Center Festival.
