The new trailer for "Transformers: Age of Extinction" warns that "The rules have changed," but based on the images glimpsed within, there's still plenty of the robotic mayhem, booming explosions and large-scale destruction that Michael Bay and his blockbuster franchise are known for.
Written by Ehren Kruger, who penned the previous two "Transformers" movies, and directed by Bay, who has directed each installment but says this fourth one will be his last, "Extinction" introduces a new human protagonist in Mark Wahlberg, playing a mechanic who gets caught in the middle of an ongoing war between rival clans of shape-shifting alien robots.
The movie also stars Nicola Peltz, Stanley Tucci and Jack Reynor. Peter Cullen once again voices Optimus Prime.
"Extinction" is set a few years after the events of "Transformers: Dark of the Moon," in which Chicago was decimated and humanity was nearly annihilated by the evil Decepticons, only to be saved by the noble Autobots and some plucky earthlings.
In the trailer, which you can watch above, a new and possibly villainous character played by Kelsey Grammer says, "The age of the Transformers is over" -- but from the looks of things, he's spoken too soon.
Optimus, for example, is as imposing as ever after shaking off some rust, and fellow Autobot Bumblee is ready to roll as well. The trailer also offers a peek at the fearsome Dinobots, who make their franchise debut in the film.
"Transformers: Age of Extinction" is scheduled for release June 27 from Paramount Pictures.
