The first full-length trailer of Transformers 4: Age of Extinction was released on March 4.

The clip starts with an beat-up truck being hauled to Cade Yaeger's (Mark Wahlberg) farm, with his daughter (Nicola Peltz) complaining about it being a superfluous purchase. As Cade gets to work on the truck, he realizes that it isn't just a normanl truck, but a transformer, none other than Optimus Prime. Cut to a bunch of sophisticated goons led by Titus Welliver come looking for Optimus Prime. The truck transforms, and out rolls Prime completely throwing off Welliver's crew.

The trailer also offers a first proper look at the main villain, Harold Attinger (Kelsey Grammer). "A new era has begun, the age of the Transformers is over," Grammer is seen saying.

As the clip progresses fans get to see "alien bounty hunters" looking to abduct Cade's daughter.

Finally, toward the end of the video, a dinobot is seen aggressively charging toward Optimus Prime. The mega machine takes the mammothian-metallic beast down with one fell swoop of his blade.

Recently Bay also shared some of the film footage with The Omelete.

Bay spoke to the publication about Stanley Tucci's character, who has not had much revealed about him so far. The director revealed that Tucci plays an inconscionable millionaire who designs and builds transformers from "alien technology." His character regards his craft building these machines as an art and equates original bots as scrap. It also seems like Tucci will serve as an element of humor. His pretensions and vanity will be attacked when he is positioned in an action sequence, and when his cowardly side is dominated, he runs for his life.

As part of the plot reveals, Bay mentioned that in a wry turn of events Cade Yaeger (Mark Wahlberg) will suddenly come under scrutiny, not only by the government but also from "alien bounty hunters."

Transformers: Age of Extinction comes out June 27, 2014.
