Actor Len Cariou has enjoyed a long and distinguished career. Among his many appearances, he created the role Sweeney Todd in the eponymous Stephen Sondheim musical. Perhaps less well-known is Cariou’s long résumé of Shakespearean roles. Early in his career, he performed in several of Shakespeare's plays at both the Stratford Festival in Ontario, Canada, and the Guthrie Theater in Minneapolis. Now, in his new one-man show, Broadway and the Bard, Cariou presents Shakespeare's soliloquies alongside apt show tunes. New York Times theater critic Charles Isherwood shares his impressions.
