Oddly enough, they don't include an original theatrical trailer, which seems to be a given these days...... the special features on a disc usually consist of this and nothing else most times. Ironically, though, there is a "showcase" track, which includes the trailers for several other flicks. Maybe they just forgot to stick it on the disc.
