The movie is 3 hours long, the book is 464 pages. A LOT more in depth
Check out all the stuff about multidimensional stuff. Figure it out and learn to actually "see" 4th dimension things in your mind. If you want a really good book to help you figure it out, get Flatland by Edwin A. Abbot. It's a really short book, really easy to read, a great satire, and with a minimum of actual math, but it explains the dimensions VERY well. Project Gutenberg has it:

Having a 4th (or beyond) dimensional dream is my major LD goal.

Probably only the math geeks here will get this, but there seem to be enough of us, so:
A mathematician and an engineer go to a lecture on quantum physics. The engineer's sitting there, listening, but he just doesn't get it. He glances at his friend, who is sitting back, smiling, taking it all in. As the lecture goes on, the engineer just gets more and more confused, while the mathematician looks like he's getting more and more interested. After the lecture the two go for a drink (alcoholic, of course (sorry, another joke)) and the engineer asks, "Did you get that?"
The mathematician replies, "Of course! It was fascinating! Didn't you get it?"
A little annoyed, "Nope. How do you understand it?"
"I just vizualize it."
"How do you vizualize something that's in 12 dimensions, though?"
"I just see it in n dimensional space and set n = 12."
