As opposed to a movie [Real Steel] where everything feels fantastical, it was really important to me, and I recognise it's not the first movie with robots in it, but that blend of naturalism in performance, writing and design with the futurism of this sport. That was the idea.

So the goal here, and we've had some early, small screenings, what seems to be kind of happening is that you come in thinking you're going to see a cool robot boxing movie, you don't expect this emotional underdog, father/son movie.
