Since the subject of Ninja turtles came up, I'd like to know how many are into (or have seen) animated classics from the 40s and 50s. Remember, these were created by artists without computer graphics. Their skill absolutely amazes me, and, IMHO, are still more captivating than most computer aided animation of today.
Disney's 'Fantasia' is one such classic. Warner Brothers also did a great job with Bugs Bunny, Daffy Duck, Elmer Fudd, etc. Neither studio produced these cartoons for children..... some of Warner Brothers' cartoons from that period had subtle (and sometimes not so subtle) political overtones.
My favorite Bugs Bunny / Elmer Fudd films are a takeoffs of classic opera: Wagner's Tannhauser (Elmer Fudd sings 'Kill the Wabbit') and the Barber of Seville (hilarious scene of Elmer Fudd and Bugs Bunny in a barber chair). If you have a chance, check out these animated classics. They are really entertaining. And while you're watching, remember that they were created totally by humans without the aid of computer enhancements.
