If you ask me, you should get some good books and tutorials to speed up your learning process. Here's some books on my list for maya:

- Learning Autodesk Maya: Foundation
- Learning Autdoesk Maya: Modeling and Animation
- Learning Autodesk Maya: Special Effects
- Maya Studios: Dynamics Book
- Mastering Maya

You'd probably need more, but those are just the books on my list. Also if you really want to master maya and make a movie like that you'll need to know some other softwares aswell I think. Hope this helps.
