10 Movie Trailers That Pointlessly Spoiled Huge Details

10. Everyone Gets Off The Bus - Speed

The trailer for Speed does a generally fantastic job of hyping the action classic up as the sweaty-palmed, high-octane thrill-ride that it ultimately is, but also gets a little over-zealous with basically spoiling the movie's very conceit.

In the hallowed tradition of '90s movie trailers that give away the A-to-Z plot for free, Speed's almost three-minute trailer flagrantly shows the ill-fated bus exploding while crashing into a plane, and the actual passengers watching the explosion from a distance, making it clear that they get off the bus and survive.

Beyond that, the trailer also spoils that there's an additional action sequence after the bus scenario is resolved, where heroes Jack (Keanu Reeves) and Annie (Sandra Bullock) battle villain Howard Payne (Dennis Hopper) onboard a runaway train, while also spoiling that said train crashes onto the street.

It's just as well that Speed is such an impossibly awesome movie that audiences wanted to watch it anyway, but the marketing team really didn't need to blow their whole wad here.
