a cartoon starring Donald Duck!
CLOWN OF THE JUNGLE title card:
Credits, including layout by Yale Gracey and B/G art by Thelma Witner:
You can watch it on YouTube:
I couldn't figure out how to do the first, opening pan B/G because of the moving multiplane layers in the foreground.
But I managed to re-create the second pan B/G, and the nearly-infinite length of this pan B/G easily qualifies it as a contender for the longest piece I've ever digitally re-created...
Here's a closer look at the left side of the pan...
And the right side (birds are obviously cel overlays):
and more B/G art from this film:
I love the subtle and somewhat abstract design of this mid-tree leafy view:
Notice the brilliant angled horizon here:
I was able to digitally remove Donald and the Aracuan bird, but that shadow refused to budge!
This pan is a right-to-left shot, and as you can see the crazy Aracuan bird appears in very first frame (on the right)...
Here's a close-up view from another shot/segment:
and that's THE END!
