How do they know it's a true story?
Well, yeah, like you said , two americans got left behind ,after scuba diving at the great barrier reef.
The movie is just , what might have happened.
They've never been heard of since, so You'd have to chalk that one up to the hungry sharks.(unless your into conspiracy theroes..then you could say they hid extra bottles of oxygen somewhere under water, and maybe those under water fan things and high tailed it and changed their indentities..)
I'm cautiously optimistic about the upcoming Batman Begins and SIN CITY movies..I've been dissapointed in movies with great trailers.
