"About the Shadow Cast. This was developed by Jason Borger just for the film, "A River Runs Through It". The cast was actually a Galloway Back Cast fine tuned and turned forward. The purpose of it was to cast a fly upstream as far as possible while keeping the line really close to the water and not having any of the line hit the water until the fly reaches its intended target. Jason did this because Norman Maclean remembered it as the best example of what his brother could do with a fly line".

Don't you see a conflict in the statements you made (see the italics). How could it have been developed (as in created or invented) if the cast was based on what someone else did? Now maybe you mean something else in which case I'll stand corrected.

Oh, and to be honest, it's documented that George LaBranche was making a very similar cast to create the illusion of an insect hatch way back in 1912 or earlier.
