This appears to be the reason for the re-shoot with Gary Kurtz and the different Wampa… But no sign of the arm prop version in the comic book being filmed.

Comic Book

I just really want to add some extra thoughts on this if you do not agree with them I do not mind as I looked at it and here are 3 things that came to mind I am not strictly speaking just some small extra thoughts.

The hero Fanfare that plays when luke cuts himself down (John Williams music) was for the roll out of the way, you can clearly hear the cue for the strike on the Wampa comes directly after the fanfare. Or atleast this is what I think. I have not tried it but I feel the music is playing earlier than it should be. Or there may be a pause (break in music) before the fanfare cut’s in.
Sound of Lightsaber retracting is leftover from the alternate edit so the sound mix was not re-done
When Luke initially leaves the cave and is climbing out the footage here seems speeded up initially and then the footage seems to go to a different speed when luke gets up to wave his arms about before falling (2 speeds all in one take).

That is all I really look forward to whatever this becomes.
