There are some movies where fans know a great deal about the story before its release, but the upcoming Transformers: Age of Extinction is not one of them. We know it is set four years after the events depicted in Transformers: Dark of the Moon, and the viral posters released earlier today indicate that the whole world is aware of these robots in disguise. Star Mark Wahlberg, who plays Cade Yeager, promises that fans will be blown away by director Michael Bay's action-packed adventure, while teasing that it's more realistic and believable than previous movies. And most importantly, the Dinobots will have a major presence in this franchise sequel.

"It's hard without giving things away, but just expect to be blown away. When we saw parts of the movie, and how it's come together, you know, you have a whole new cast, you have a whole new threat, new enemies and all the things that you liked, with all the explosions and the action, but it's just a little bit more realistic, a little bit more believable, I think."

The actor went onto tease the "elaborate" recruitment of the Dinobots, and that fans can look forward too seeing more of them in forthcoming sequels.

"Recruiting the dinobots - it's pretty elaborate in how it happens. [It's] not like Optimus has a whistle and they come running, he's really got to convince them to come onboard and fight this fight, and it's pretty cool how it's done. I think people are definitely going to get their money's worth, it's well worth the wait. And I think, for the die-hard fans, they're going to have a whole new thing to look forward to in the future."

He also talked about how some movies "trick" the fans with their trailers by showing the best parts of the movie.

"The only details I can give you are the ones that are already out there. I think a lot of time, moviegoers are kind of tricked by trailers. They'll see a cool moment and go, 'Oh, I can't wait to see that,' but once they see [the trailer] they've seen the best bits of the movie."
