'Tomorrowland' trailer: George Clooney ups the action, zaps androids

George Clooney and Britt Robertson battle androids in the new 'Tomorrowland' trailer

In a summer movie season chock-full of world-saving superheroes, rampaging dinosaurs, globetrotting spies and time-traveling cyborg assassins, it seems that outsize action set pieces are all but required. Now Disney's sci-fi adventure "Tomorrowland" has obliged as well.

After a steady progression of enigmatic teasers, the latest trailer for the Brad Bird-directed movie showcases George Clooney and Britt Robertson battling it out with ray-gun-toting invaders in footage that  closely parallels what was shown at New York Comic-Con in the fall.

Set for release May 22, "Tomorrowland" pairs jaded scientist Frank (Clooney) with bright teenager Casey (Robertson) as they travel to a high-tech wonderland and try to fix the future before time runs out.

In the new trailer, which you can watch above, Casey makes her way to Frank's doorstep and demands his help. Just as the grumpy genius begins to scold her, his house is besieged by a squad of overly polite guys in gray coveralls. Frank puts the house on lockdown, but the baddies manage to blast their way in with glowing weapons.

Frank and Casey are no pushovers, though. They shove one adversary — revealed to be an android of some sort — halfway through an interdimensional portal, zap a couple more with a laser grid, and pin another to the wall with a giant electromagnet. Then all that's left to do is blast off to the titular Tomorrowland in a flying bathtub.

"You ain't seen nothing yet," Clooney says in one of the trailer's most trailer-y moments.

He's right too: Although moviegoers have now glimpsed some pyrotechnic action to go with the retro-futuristic imagery, much of what Bird and co-writer Damon Lindelof ("Lost") have in store remains mysterious. But how they try to strike a balance between wonder and adrenaline, and how moviegoers respond, will be revealed in the very near future.
