In 2001, filmmaker Ken Burns turned his documentary lens on Mark Twain. This is an acclaimed film and an excellent introduction to Twain's life. Actor Kevin Conway portrays Twain during the film.
This 1967 film is as close as you'll come to seeing Mark Twain speak on film. Was Twain camera shy? Nope. Just dead. Talking pictures came after Twain's death in 1910, so Hal Holbrook's one-man show is the next best thing. The script is almost entirely comprised of Twain's words, and Holbrook nails Twain's voice and mannerisms.
Sure, this flick isn't exactly what you'd call good, but it stars former teen heartthrobs Jonathan Taylor Thomas and Brad Renfro, and that's gotta count for something. It's a Disneyfied version of Twain's two best-known stories.
The dashing Errol Flynn stars in this version of Twain's first entirely fictional work. Two identical boys are born at the same time, but one is a prince and the other is––you guessed it––a pauper. When they switch identities, mayhem ensues.
