I just came across an article on ew.com proclaiming it the Best Movie Trailer in 2006.

Here is the citation about this trailer:

GOLD
Little Children
We never hear the words infidelity or cheat or affair but we know that something nefarious is going on, and the omnipresent sound of an approaching train tells us a collision is imminent. Could win short-film award, it's so good.

What do you guys think about it?

If you are interested, I have posted a review of this film in my Reviews section earlier this year.
