A living, breathing, American masterpiece! It is, quite simply, one of the most acclaimed and enduring performances in the history of theater. Fifty years ago, a young actor took the stage in a tiny off-Broadway theater and introduced the world to a man they would never forget. The actor was Hal Holbrook, and the man was Mark Twain. “Mark Twain Tonight!” is a one-man play devised by Holbrook, in which he depicts Twain giving a dramatic recitation selected from several of his writings, with an emphasis on the comic ones.
