The Telegraph has posted their interview with Neil Fingleton for Game of Thrones. When asked how playing a giant compared with his role in 47 Ronin, he said:
47 Ronin, with Keanu Reeves, was fantastic. Keanu Reeves is a really nice guy, and I got to work with him every day, as all the fights my character, Lovecraftian Samurai, were in were with him. Each day, the stunt-co-ordinators would put a fight together, and me and Keanu would have to learn the fight.
