Help figuring out the name of a movie?

I started watching the movie a very long time ago and I could never finish it. The movie scarred me for life so I am bound to remember what little I do. I NEED to watch it to get the nightmare over.

Okay here is what I remember:

-It was about how a fictional world was about to end because The Thing was going to destroy everything. The Thing was like a storm that wiped everything out.

-Only one person could save everyone, a little human boy.

-He is helped along the way by a giant (golem?) and several animals(?)

-His main enemy is e Beast that sleeps in a cave and as far as I remember it was terrifying.

-Near the beginning of his journey he;s riding a horse, which drowns in quicksand.

-At one point he is helped by what I think was two dragons, which saved him from the beast when the horse drowned.

-Later he has to face two giant statues that he has to go through, and he cannot fear them or they kill him (with laser eyes?)

that's as much as I can remember... please someone save me D:
