There’s also the legendary lost “insect pit” scene from the 1930s King Kong that had people puking in their seats.
Kong had just thrown the sailors into the ravine who were on the tree. From what I have heard giant spiders go after them and finish them off.
Personally, the scene where the guy climbs up the tree to get away from the dinosaur gave me nightmares for years, that and when King Kong breaks through the giant door.
It’s on the Blu-Ray. Apparently, Peter Jackson and his friends re did it.
Cheers,
