 Warwick Davis as Nikabrik, a black dwarf. He is descendant of Ginarrbrik, who served the White Witch, and bears one of his rings, which was passed down from each generation. Mark Johnson acknowledged casting Davis as the treacherous Nikabrik was casting against type: Berger covered all his face bar his eyelids in prosthetics, to allow Davis to ward off the audience's perceptions of him. Nikabrik's nose was based on Berger. Davis feared filming in the Czech Republic, because the grass is filled with ticks, so he put elastic bands to hold his trousers against his legs. Davis portrayed Reepicheep in the 1989 BBC production of Prince Caspian.
