Replying to Mysterious Movie Trailer

I dont know if this has already been posted but I went to see transofrmers with a friend of mine and of course we were right baked. Anyway, the previews start up and it starts into this one that almsot exactly mirrors some kind of beer commercial, its shot through a home video camera and its at a party. Theres beer, music lights and of course hot chicks. Thats when shit starts getting fucked up. All of a sudden explosions start happening all over the palce. the music stops and people start screaming. The camera pans off the deck into downtown New York which begins to become enveloped in fire and explosions. Theres shit flying all over the place and the camera blacks out and reappears with people rushing into a basement, theres screaming crying and absolute panic. The preview ends with no title, only a black screen and a date, and of course in my blazed state and trying to absorb what i just saw i have subsequently forgotten it. The epic ferocity of the preview just got to me so much and ive looked on youtube to try and find it with no avail. does anyone know what im talking about?
