Duhamel's list of injuries included two busted ankles, which he hurt during his lunch break, and the army professionals he was working with didn't let him live it down.
He tells E! News, "I actually got a little bit hurt this time (in this movie), not because it was dangerous, but because I'm a klutz. I sprained one of my ankles before lunch and then after lunch I sprained the other. I'm not kidding you. I sprained not one, but two ankles in the same day. My nickname amongst all the actual Navy SEALs on my team became H.R. Stumblesnstuf."
