Here’s “Willie the Kid,” another UPA cartoon with dissolving backgrounds. Ah, but that’s not all. The colour changes, too.
I’m sure because the UPAers intended this as Art, the colour change means something. For a while, I thought the green represented the real world, while the brown represented the pretend world. But the kids are playing Old West when it’s green, too. And then there’s a rose colour during some scenes. Oh, well.
Some of the animation is by Bill Melendez, who went on to make kid-character cartoons that actually had some charm, unlike this one.
