I just saw a tv spot during That 70's show on FX and it showed a little bit of new footage and a new tag line, which with the eeriness of the trailer fit the tone of the movie well.
- The trailer started with a shot of the Predator ship heading for Earth
- Shots of Molly and Kelly, the town etc., mixed with the words: "On Christmas Day, The Last Place We Want to be.... Is in the middle...".
- A shot of the National Guard walking down the street and an alien violently grabbing a soldier and picking him up off the ground (ala Dietrich in Aliens but from the side)
- Shots of Sheriff Morales saying that the town needs to be evacuated (the acting IMO seemed pretty believable.. )
F*****G Awesome!!
