“Progress is a little slower than i had anticipated. Finishing this damn wampa is proving more of a pain that i’d hoped, but it’s getting there. It didn’t help that, while watching the final workprint, i noticed that two shots i had thought were complete were missing a couple of elements, so i needed to get those filmed and added into the compositions.
I assure you i am working as fast as i possibly can, but there is no possible way this can be completed before the end of this month, and that is if everything continues without any holdups. But the end is in sight and will be just a few weeks away.
This means there will be no break for me after ESB:R is completed. I will be starting work on ROTJ the day after ESB is released.”
