I'm thinking of creating a rough cut based on this idea, which I'm sure has been suggested before:
I'd like to kill off Qui-Gon in his first duel with Darth Maul on Tatooine. This way, we can skip a lot of the boring dialogue on Coruscant, handily cut out the midichlorian explanation, make Maul seem like more of a threat, and make Qui-Gon's funeral more tragic. I'll try to make a draft of the death seen later on.
