Like his Sons of Anarchy character, he's into motorcycles, and he rides a Harley. Talking about riding, he's said, "You smell the scents of the city, the garbage, the flowers, and bread baking. I feel more engaged in the world on a bike. That's the romantic side of it."
Charlie isn't afraid to defend himself, either. He's said that he keeps a machete in his office, and when a burglar came into his house, he challenged him: "I pinned him to the ground and said, 'Dude, I'm not going to f*ck you up this time, but if you ever come near here again, literally, they'll never find your body — I'll cut you in so many pieces.'"
