Bay spoke to Entertainment Weekly on April 11 about the film. The director said that the franchise was in some way moving into a completely new phase, which could be detached from the previous films.

"It's kind of like a new Transformers," Bay said. "We had three, the first trilogy, and this is going to be the next one."

When the director suggested that it was a trilogy, he did add that he wasn't sure if he would see it through.

"Yeah, it's the first of a new trilogy," he said. "I'm not necessarily sure that I'm doing [the others], but that's what it's meant for."

While there has been a lot of conjecture surrounding the future of Optimus Prime, it had also been previously rumored that Prime might die in Age of Extinction, Bay suggested that the main hero will succumb to the vicious ways of mankind. The director said that Prime will be "angry" this time around.

"He's done good for earth, and he's been f-ked over," the director said.

Bay also spoke about taking Michael Bay on, and in a way, replacing Shia LeBeouf with him. The director suggested that it was time for LeBeouf to move on.

"It's all good. He's a good guy, but three movies, the same guy, it's time, you know what I'm saying?" Bay said. "It's always good to freshen it up and change the story."

The director added that after having worked with Wahlberg on Pain and Gain he felt he'd make for a good fit. "Then I pulled Mark into this after Pain & Gain, because we had a great time working together," he said.

Transformers: Age of Extinction will release on Jun. 27 2014.
