This is the final cut of the Sleep Dealer trailer.
The trailer went through many evolutions, alternate edits, and bizarre internet leaks before the distributor locked and released a theatrical version. This new cut was made for the DVD release. I worked on it myself, and so I suppose this is the 'director's cut' of the trailer.
