Funny, I've never noticed all the skulls in this movie (mushroom cloud, waterfall, etc) anyway...

The waterfall thing is a tough. Seems line the only way to do it - which is probably a pretty big job - is to somehow drop a cliff (in place of the waterfall) behind one of the shots (1:29:30 or 1:30:06- ish) where the vehicle is falling down one of the falls. This would go right after they go off the cliff. This shot would also have to be flipped. Anyway, this way we could see them fly off the cliff and hit the water and climb back in. Then we could cut the Ox and Mutt dialog, drop their asses again and again if we wanted to in quick succession. Or cut the three times it drops thing all together and go straight to them walking to the rocks after the third fall.

Easy for me to say, huh?

I've only just found this forum today and read to page 3 so I may be too late on this, but I have an idea for the waterfall sequence. I don't know if anyone has seen the comic adaptation, but they were smart enough to realize the CG tree was stupid, so they got rid of the cliff altogether and had the river running right through the area where the and scene takes place at the same ground level ... so the amphibious vehicle just drives off the bank and into the water. It seems there might be a way to edit the sequence to give this same impression. I'm going from memory here, but I think you'd have to cut the bit where Marion drives by the edge of the cliff and notices the tree offscreen ... and you'd have to cut comments about the cliff ... but otherwise you might just be able to show her speeding towards the edge of the cliff and cut directly to the driving off the tree into the water. A CG replace of the tree with the cliff edge would likely resolve the whole problem.
