Watch MoviestoWatch. Recreating the one-man show he starred in on Broadway, Hal Holbrook portrays Mark Twain as a 70-year old humorist who skewers politicians, newspapermen and so-called patriots in this 90 minute monologue. Holbrook adapted Twain's own words for a commentary on slavery, religion and politics, mixing the satire with comic yarns about life on the Mississippi and a very effective ghost story. The show's highlight are the lengthy passages from "Huckleberry Finn".
