The first person who tabed this theme song was a little off in my opinion. The 15s on the G string are too high. I found that if you play fret #4 on the A sting, fret #5 on the D string, and fret #6 on the G string; it sounds more like the movie. 

G|----------------
D|----------------  Play at a slow tempo
A|----------------
E|-0h1-0h1-0h1----

then

G|----------------
D|----------------  Play at a fast tempo
A|----------------      Play about 15x
E|-0h1-0h1-0h1----

then

G|---------6
D|------5---
A|---4------
E|----------

Thats it. Correct me if I'm wrong, but I think its right.
