Ryan Kwanten on circa 'Summerland' Zef

Before you starred in True Blood, you starred as a surfer on the WB's Summerland, opposite a very young Zac Efron. What do you remember about him?
I always remember that he already had, at that age, a really good work ethic. With young actors coming up you also look at how in tune with the world are they — i.e., could it get to their head? I felt like he had this really old-soul quality to him.

He's pretty buff now, too. What would happen if the two of you arm-wrestled?
Oh, I'm a pretty dirty fighter, so I dare say I'd have him.
