The first trailer for the not-really-a-reboot, Transformers: Age of Extinction, has been released, and it has Michael Bay’s signature all over it. While the new movie follows after the events of Transformers: Dark of the Moon, we get to meet an entirely new cast of characters this time around, and some huge new Transformers, too. As far as we can tell, the only characters to appear from the previous three movies is Optimus Prime and Bumblebee—new to the big screen will be the Dinobots, which are part of the Autobot faction.

The explosions are big, the slow motion is dramatic, and the main characters shout—a lot. We get quite a few looks at the new Transformers coming to the big screen, including Grimlock (the T-Rex), who is often considered the leader of the Autobots. The film stars Mark Wahlberg in the leading role as Cade Yeager, Nicola Peltz as Tessa Yeager and Jack Reynor as Shane Dyson. Other notable names include Kelsey Grammar and Stanley Tucci.

Transformers: Age of Extinction is scheduled to to hit theaters on June 27, 2014
