Wallström reveals that he came to this episode with plenty of prior chopping experience. “That was part of my audition for getting the part,” he jokes. “They asked me if I could chop wood, I said yes and got the part!”
Gags aside, the actor says he really did swing an axe as a teenager, although he did take a refresher course of sorts before filming this episode.
“Back in February or March, I got a call from Sam and the team saying, ‘Hey, can you start practicing doing some wood-chopping?’ I got this great Dutch guy to teach me, and chopped a lot of wood for him. I have some skills now! It’s on my IMDB page.” [x]
