We know it's being referred to as the robot boxing movie [Real Steel], but truth is, 70% of the movie is the relationships.

There is a reality to the way the actors play the scenes, given that there is a real, animatronic, moving robot in the room. So the level of nuance and realism in performance was higher because we built the real ones, and it keeps the visual effects guys honest.

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.

And this movie [Real Steel] definitely looks like nothing else I've made, which was the point. I think also, Evangeline and Hugh are such a fantastic... Their chemistry is so genuine. And also it's a good balance to all those visual effects. It'll give you more of the tone.

I would say, while I think audiences are savvy enough, I think that the effects work in the teaser is quite a bit more than presentable. I think they look good and representative of the film. The harder thing with the teaser, interestingly enough is, how much to show.

I've learned that, I wouldn't say I've made that mistake, but I've learned on some of my other movies, like, you always want to show everything that you feel works
