Hal Holbrook and his works provide examples of:
- Author Appeal: His love of Twain is boundless. He stated in the Ken Burns documentary about the author that anytime he was feeling down, he'd open up one of Twain's books to any random page, start reading and immediately feel better.
- Dawson Casting/Playing Gertrude: Although Holbrook started playing Twain when he was in his late 20s, he was 92 when he retired from the role. Twain died at the age of 74.
- Reports of My Death Were Greatly Exaggerated: Holbrook once told the story of the time a friend of his got lost on the way to visit Mark Twain's grave and asked a man for directions. The man pointed them in the right direction and then said, "You know that actor who played Twain, Hal Holbrook? I think he's buried someplace close by."
