"No, no. It wasn't the airplanes. It was beauty killed the beast" says 1932 Jack Black literally two minutes after airplanes definitely did kill the beast. With machine guns. Before falling 102 stories.
But really, what I liked most about King Kong was its special effects. Since he was claymation, every time they'd move his model to set up the next shot they'd unavoidably mess up his fur. It gave it this crazy motion effect. Look around his shoulder blades in this shot—
The effects really weren't that bad. They were pretty impressive actually.
It'd often look like they were projecting the claymation onto a screen behind the actors.
And they'd find ways for Kong to interact with the cast. Like when he's holding Ann, she's in a mechanical arm while the claymation somehow plays in front of her.
The only time the effects were pretty bad was anytime they'd show a close-up of his face. Is it a man in a mask, is it mechanical, what's going on here?
For everything from special effects to story to acting, King Kong was a ton of fun to watch.
