Ah, to heck with it. I couldn't wait.
Here is a rough example of what I'm planning to do:

(Note: Photobucket shrank the images from the original 1920x1080 dimensions. But you can click on the links above to see larger versions.)
The top image is the absolute worst frame from the first shot of the Treadwell scene. The bottom image is the same frame after clean-up. Using information from about a half-dozen other frames from the same shot, I was able to reconstruct something that might be useful.
When I start a dedicated thread at a later time, I'll go into more detail. Because it's more than just clone-stamping in Photoshop.
