What happens to Odysseus when he meets Charbydis?

In the epic poem:

Odysseus orders his men to steer away from Charbydis, and as such sails past Scylla instead.

In a particular movie adaptation:

The entire ship goes over a waterfall and into Charbydis mouth. Odysseus is able to escape by hanging onto a branch, and waiting until Charbydis expunges the water with some of the wreckage of the craft. He ends up adrift until Calypso finds him.
