Zac Efron: I Put In the Work for 'The Lucky One'

Zac Efron definitely put on some muscle for his role as Marine Logan Thibault in The Lucky One.

The 23-year-old actor caught up with MTV about how he really prepared for the role of a Marine.

Zac shared, “I knew that, the second I went to camp and met some real Marines, that I didn’t have that presence that they possess. They have this way about them, and they’re like 50 lbs. heavier than these guys [actors]. I started training immediately, to do the best I could.”

He continued, “Its a part that’s kind of sensitive. I cared too much about it to just let it slide, so I really put in the work.”
