Vin Diesel is an enthusiastic one. That’s for sure. During a recent interview for his film The Last Witch Hunter, the Fast & the Furious star decided to flip the switch and ask me what I thought about the action/adventure flick. I compared him to his character Kaulder, a man who is immortal and indestructible but faces loneliness and isolation. There’s a facade the character puts up, all the while consumed by weakness. In many ways, Diesel shares similar traits.
