No doubt at least most of us Looney Tunes fans have seen Chuck Jones's "What's Opera, Doc?". Well, this short documentary explains what all went into it. It just goes to show what an amazing cartoon it was, spoofing Richard Wagner's "Ring of the Nibelungen" while at the same time celebrating its magnificence and splendor. It was clear from early on that the people making the Looney Tunes/Merrie Melodies cartoons liked to work with classical music - just watch "A Corny Concerto" - but when you see the work that went into this one, you truly realize what an accomplishment it was (and remains): the script, the direction, the animation, the layout, the music, the sound effects, and Mel Blanc's and Arthur Q. Bryan's singing.
All in all, "Behind the Tunes: Wagnerian Wabbit - The Making of 'What's Opera, Doc?'" does a very good job looking at the creation of this grand masterpiece of animation. And above all, there will probably never be another cartoon like that in our lifetimes.
