-Regarding those Elephant things from LoTR, they looked less like elephants compared to the Goliaths here, and were much bigger (and slower and uglier).

-Regarding the Grimm, I believe Monty didn't even plan on using them, he just added them to get a cheap justification for the existence of Grimm and to add not-really-important-to-the-plot fights here and there if he wanted.
