How Do You Make a Trailer or Promo That Competes with Hollywood?

Boing Boing SuperStar Blogger and all around nice guy CORY DOCTOROW did a great post this morning about the Return of the Moon-Nazis from Star Wreck creators but he didn't really talk about the Kick ASS emotionally compelling Teaser Trailer that looks like it was made by a Hollywood Movie Trailer company.

Do you know of any other Independent Online Video Trailers or Promos that are "Key Art" Award Winner Quality?
