Fox spent a hell of a lot of money on this movie, I don't think they would set it up to fail with a weak ad campaign (unless this was being distributed by Dimension Films). I think we're going to see a 'plan of attack' very similar to Freddy vs. Jason, a film which had only one trailer released two and a half months before it's theatrical date and still made some serious box office coin. The final trailer for AVP should hit in June, we've already got posters and theater displays showing up across the country, all that's needed is some healthy publicity through TV ads and newsprint publications (Fangoria has a cover story, expect Starlog and various entertainment magazines to do the same) and everything should turn out fine. My only concern right now is the rating.
