In the latest trailer for Disney's "Tomorrowland," Casey Newton (Britt Robertson) must get to Tomorrowland to save the future.

With an ominous narration from Frank Walker (George Clooney), the trailer warns the future is running out -- and that Casey might be the only one who can save it. After she discovers a pin that shows her a bright, alien world, Casey hunts Frank down so that she can find that secret place, only to find herself hunted down by enemies willing to kill. Filled with advanced technology, explosions and the first appearances of Hugh Laurie, the trailer offers a deeper glimpse into the story.

Directed by Brad Bird, "Tomorrowland" debuts on May 22.
