ABC is airing a special on UFO's, the network is a part of Disney. Disney owns Touchstone Pictures. Touchstone Pictures is releasing "The Hitch Hikers Guide to the Galaxy" in April.
Basically the special airing tonight is a part of the marketing for "The Hitch Hikers Guide to the Galaxy". It's sole purpose is to generate buzz about UFO's and aliens as a prelude to the movies release.
This is one more reason why Main Stream Media is scum... Priming the pumps with rehashed "journalism" to market a movie.
Either that or it's all a coincidence.
