There's a very interesting article or symposium to be written on just the real difference between comedy filmmaking and non-comedy. Because, you know, when you work in comedy, you depend on audience screenings to tell you about your movie.

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.

If you go to any fight, whether MMA or boxing, there's a whole musical soundscape to these events. There's pre-event pump up/psych-up music, there's fighter introductions, there's between rounds, so my musical needs are really diverse.

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

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.

I'm not sure that I could give notes to someone that I revere. That's a general challenge of directing, giving notes to someone you revere. The other big contribution to this, which most people I show footage to take note of is Mauro Fiore's cinematography is unbelievable.

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.
