This is mine. Hilarious. YouTube - Lilo & Stitch: Aladdin Teaser Trailer 1 of 4 Very funny! And of course ROTF...but that's a given.
I was fourteen and watching Stargate when this trailer premiered. I was never so excited in my entire life for an upcoming movie.
This.... So much in fact that it inspired me to make this as my final college project back in the late 90's YouTube - Fallen Angel Oh and a close second would be this without a doubt, especially from 1 minute and 40 seconds onward. YouTube - LOTR: The Two Towers (trailer)
The Teaser for Star Wars Episode 1. I like watching it from time to time. Plus trailers for the upcoming Star Trek Movie. There REALLY good! And all three trailers for Transformers. They never get old.
7 posts and no mention of the awesome T2 teaser? YouTube - Terminator 2 "I'll be back" 1990 promo teaser trailer Just needs a TV series version with a factory full of naked Camerons.
