Comparing The Lost World (1925) and King Kong (1933)

The Lost World is Willis O'Brien's first venture into feature length stop-motion animation.  He will of course create one of the most iconic "performances" on film in King Kong eight years later.  But I couldn't help but notice some eerie similarities between the films.  Did you notice:

1. Dinosaur Animation.  It's obvious, but both films feature Willis' stop-motion animation of dinosaurs.  The battles here are more abbreviated, but already the animator is imbuing his creations with personality.  See the brontosaurus' snarl as the allosaurus prepares to attack.

2. A driven self-promoter whose hubris becomes his undoing.  In The Lost World, Professor Challenger is obsessed with finding the dinosaurs to prove his value to the scientific community and then, when the opportunity presents itself, he brings one back home to London.  In King Kong, filmmaker Carl Denham is obsessed with showing the world this uncharted island, then decides to bring the ape back to New York.

3. Bringing large, untamed animals to populated areas is a bad idea.  Challenger's brontosaurus and Denham's Kong both run amuck in densely populated areas.  At least it ends better for the brontosaurus.

4. Monkeys love women.  One of the side stories in The Lost World is a monkey's devotion to our heroine Paula.  In King Kong, same thing but with a larger primate.

5. Walking across logs doesn't is not advisable.  When the fellowship in The Lost World crosses a log to enter the land of dinosaurs, one of the creatures knocks the log over, stranding the group.  In King Kong, our title ape removes a log bridging a chasm to attack the human invaders to his land.

6. Remote areas are ideal breeding grounds for monsters.  Skull Island and The Lost World's plateau both use natural elements to shield their unusual denizens from easy discovery by the outside world.
