Hades from Hercules. He falls into the River Styx, and while, as a god, he can't die, Pain and Panic make it pretty clear he probably won't be able to escape for quite some time.

Enchanted, Queen Narisa turns into a Giant Purple Dragon, falls off a building, then explodes into glitter.

Pirates of the Caribbean: At Worlds End, Davy Jones has his heart (which exists outside his body) stabbed, and he falls into the Maelstrom.
