I wonder if they used a wire frame or a metal endo-skeleton for the body. From the perspective of a Ray Harryhausen fan this figure looks amazing. No visible joints, a pretty good likeness of Butler; I think Hot Toys will be getting more of my money.
My only fear is that the body will deteriorate over time or might tare from usage but I hope HT would take that into account.
I would love to have a head and helmet with a scar from after Leonidas fought Kurgen. Maybe those will be extra accessories.
