Mark Wahlberg sheds more lights on what to expect from his upcoming action film "Transformers: Age of Extinction", AceShowbiz reported. The "Lone Survivor" actor says to the Daily Beast that the fourth movie will be more emotional and reveals the background story of his character in the process.

"He'd had a child when he was in high school and his wife passed away, and the promise he'd made to her was that she wouldn't date any boys until she graduated and that she'd be at the graduation - because we weren't due to the pregnancy. So there's an anchor to it and a realness to it that I like a lot."

"It was a tighter script, and its own stand-alone thing. I think the emotional core of it, the human element, is going to be extremely powerful. It's an ordinary man trying to do extraordinary things to save his daughter and keep her alive - and this boyfriend he didn't know anything about," he says.

Director Michael Bay did once say that the new film will be less goofy. "I wanted the first Transformers to be very suburban and less cool," he explained. "This is a much more cinematic one. I focused on keeping this one slick. There won't be any goofiness in this one. We went a bit too goofy [on the last one]."

The film is due on June 27, 2014 in 3D. In the upcoming fourth installment, Earth is scarred by the events of the past three movies but is moving on after all the giant robots disappeared.

Wahlberg plays Cade Yeager, an inventor, who discovers a buried Transformer which sets the stage for the return of the rest of the Transformers. Nicola Peltz plays his on-screen daughter, Jack Reynor portrays her boyfriend, while Kelsey Grammer is tapped to take on the villainous role.
