I was watching DE's excellent edit this morning and I remembered one thing that might use your expertise. Right before the Falcon blasts it way out of Mos Eisley, Han and a bunch of stormies exchange some shots, there is some stuff blowing up and they take off. The trooper closest to the falcon is running towards the falcon when an explosion behind him knocks him over. The only thing is, he's just jumping in the air, he topples over and lays there. It just looks goofy. And the take is repeated in the film, so you see the same action cut in pieces. Is there anything that can be done with this? Maybe a blast actually hitting him or some debris knocking him over?
