How Mark Wahlberg Scrambled to Get in Shape for Transformers: The Last Knight

For Mark Wahlberg, one of the most impressive transformations in Michael Bay's "Transformers: The Last Knight" happened off-screen.

"I just go off of 'Patriots Day' so I got as heavy and out of shape as possible to play that part," Wahlberg tells Made in Hollywood reporter Patrick Stinson. "Then I had three weeks until I started to shoot this movie. When Michael saw me he went a little crazy."

But Wahlberg promised the director he'd melt away those pounds from playing a Boston police sergeant and be ready for action -- and more action.

"I just continue the routine throughout the entire movie, the healthy diet, no drinking wine, exercising, running every morning," says Wahlberg. "It's not about looking like you're in shape. It's also about being able to perform these kinds of stunts and action sequences 12 hours a day for five months."

In the fifth and apparently last installment of the blockbuster franchise, humans are at war with the Transformers, and Optimus Prime is gone, so it's up to the unlikely alliance of Cade Yeager (Wahlberg), an English lord (Anthony Hopkins) and an Oxford professor (Laura Haddock) to save the world.

Wahlberg says the movie sneaks in some comedy in between the mayhem.

"I love the fact that (Cade) is thrown into this whole other world," the actor says. "He's kind of a fish out of water, with all the opportunity to create a lot of humor and laughs, paired with this upscale English professor, dealing with with Anthony Hopkins, and the fact that he's decided to go off on the run to allow his daughter to be reintegrated into society, have a chance to go to school and have a normal life. So I just thought it was cool."
