To give a better example of Chuck Jones' later work than the aforementioned "Father of the Bird" or "From Hare To Eternity", I'd like y'all (yes, I'm a Texan, I can say 'y'all') to check this out. This TV special from 1975 was independently produced by Chuck Jones. It has nothing to do with Looney Tunes, but I consider it one of Chuck Jones' finest works. To call it a "cult classic" may be a stretch, it's more of a "classic nobody ever talks about".
Chuck Jones loved literature, written for both children and adults. In the 1960's and 70's he did several animated adaptations of stories by the likes of Theodore "Dr. Seuss" Geisel ("The Grinch, "Horton Hears a Who"), Rudyard Kipling (this piece and a few others) Charles Dickens ("A Christmas Carol") George Selden ("The Cricket in Times Square") and Norton Juster ("The Phantom Tollbooth"). I'm not sure if he ever tackled Mark Twain, whom he constantly cited as a source of inspiration, but I digress.
Some of these specials were wonderful, others were surprisingly boring. But I'd rank this one, "Rikki-Tikki-Tavi", right up there with with his Seuss adaptations as the best of the lot. I'll warn you...it's faithful to Kipling's dark story, so if you are looking for something like Daffy Duck or Road Runner, you may be surprised by this. Enjoy the wonderful animation, and the narration by Orson Welles, and experience the "serious side" of one Charles M. "Chuck" Jones.
