An accident-prone, self-proclaimed stuntman eager to earn the money needed for his abusive stepfather's life-saving heart operation hatches a plan to jump 15 busses in a comedy scripted by the Lonely Island team.
An example of a terrible trailer: too long, shows too much of the movie, tells the whole first half of the story...the only thing that this has going for it is that it intentionally does not show any of the dinosaurs in its entirety.
The great film trailer for the 20th anniversary re-release of the "Star Wars" films (the original trilogy). I remember that the entire audience would go berserk every time it came on, in any theater, before any movie.
It doesn't seem like much now, but this trailer for the Ringo Lam-directed action film was groundbreaking in its day, for being cut so precisely to the music (the Prodigy's "Firestarter"). It certainly made me see the movie.
