What's 3D Animator's job in film-making?

[notgonnatelute]

Didn't know where to put this question but hey animation has something to do with VR .

So I am wondering what does 3D animator do in filmmaking industry?
I'am in doubt does they for example make some huge bridge collapse(which would be crazy to do in RL) and later its edited in movie or 3D animators are just stuck to looney tunes style cartoons?

The movie Avatar? All of that.
Transformers? Most of that
The Hulk....him too.

Anything that can't happen in real life (and some things that can)...all of that.
