Talk about a teaser. This is exactly what South Park was lampooning in the episode where the kids are waiting to see the Terrence and Phillip movie teaser trailer. Truth be told about this trailer though, this is basically an announcement trailer if nothing else because they had not even shoot a frame of film when the trailer was released. Tomorrow the same with the next trailer!
That said, I LOVE the tagline "You Will Believe A Man Can Fly."
