Hanna-Barbera made one of its rare forays into prime-time entertainment with this way-out, way-ahead-of-its-time mash-up of American literature and fantasy adventure that mixes live action and animation. Set during the events of Mark Twain's classic Tom Sawyer, the series places Tom Sawyer (Kevin Schultz), Huck Finn (Michael Shea) and Becky Thatcher (Lu Ann Haslam) in deadly peril following Injun Joe's (Ted Cassidy) escape from the courtroom. Spotted by the revenge-minded renegade on a dark and stormy night, the trio flees into a cave and plunge into a series of fantastic adventures, each rendered in a unique style of animation. But whether they are in La Mancha, Lilliput or Ancient Greece, they continually encounter murderous villains, miscreants who all share the same face -- the face of Injun Joe!
