Currently promoting his latest movie The Lucky One – the 24-year-old actor plays a marine who serves in Iraq and goes to North Carolina to search for a woman he thinks brought him good luck.
He dished on how he trained his body for the role.
“Physically I started eating a lot. Eating through walls. Just eating and eating. That’s all I’d do and I put on some weight that way. As far as the training goes, just trying different techniques and methods. It’s one of the only concrete things that you can do to feel differently about a character. I didn’t feel like a Marine. I didn’t have the posture. I didn’t feel like I had the presence and that was just one thing for me that I could do to really up that change.”
Zac also met with real marines and thought it was “awkward”.
He explained, “When I went in to meet some of these guys, the sergeants, I was blown away. I was taller than most of the guys, but they were just thick, like there was something about them. They had a definite presence. Here I am, slouched over and I just smile a lot. I’m just always smiling. These guys were always serious. Honestly, it was one of the most awkward moments in my entire life.”
