When I first saw the film in theatres I remember watching the big arm structure they were on plummeting to the bottom of the lava fall and thinking "why didn't George have Anikan go over the lava fall with the structure?" They even linger on the shot of the arm structure plummeting to the bottom of the lava fall so that gives you the required screen time for the audience to hear Anikan's screams as he plummets to the bottom with the structure. I also like the idea of Anikan going over the lava fall, because it is more in line with how I imagined Anikan getting injured, and how George originally described it. In the early rough story boards in The Making Of ROTS book it shows Anikan losing his balance and falling into the lava. Obi-wan originally didn't cut his legs or his arms off, they were burnt off by the lava. This would also make the way Anikan ends up in the suit even more graphic, because we don't really get to see what he went through trying to get out of the lava, and what what kind of agony he was in while attempting to do so. When we see how bad he is injured when he is found by the Emperor on the bank it is left up to the audience to imagine what bad things happened to make him look like that. I like this idea and will attempt to do a quick edit of this so everyone can get a general idea of how it would look completed.

Also, about how to fix the jump that will occur in the music if you make the duel end by Anikan going over the lava fall, have everything go silent as the arm structure tips over the edge of the lava fall, and all you hear is Anikan's screams as the arm structure falls down the lava fall and when the arm structure hits the bottom of the lava fall just have the screams fade also. Then you could cut to something else. I will try to do a rough edit of this.
