They just don't make 'em like they used to.

I love the old Max and Dave Fleischer cartoons, especially the gritty, trippy older ones like this. They invented the technique of rotoscoping, or animating on top of live actors, along with developing the first sound cartoons (four years prior to Disney's famous Steamboat Willy). The Fleischers' early sound efforts didn't get as much notice and success because most theatres weren't equipped with the speaker systems to support their earliest "talkie" or "talkartoon" efforts. But with characters like Betty Boop, Popeye and Superman, they enjoyed quite a bit of notoriety and success throughout the years.

And come on, who doesn't like Cab Calloway? Huh? No one, that's who. Even Danny Elfman is a fan of this cartoon.
