This is fascinating. The airbrushing that you see and is being criticised came about for a couple of reasons. One creative and one technical. As I said we needed to create a look for the film. Matthew Vaughn had originally wanted Kick Ass to look natural and real. After all the whole point of Kick Ass is he lives in the real world, not Gotham city, and has no superpowers. So the best way for people to relate to him was for them to recognise the world of the film as everyday and not stylised. The problem with this was it just didn't look very sexy, and Matthew's mantra became,'make it look like Transformers'. Now you have to realise this came after the film had been shot, so there was no strong backlight and this was Toronto in the winter, not L.A. in summer. Then the technical reason. The film was shot on film, mostly 500asa with anamorphic lenses. This meant fairly big grain to begin with. Matthew asked us to brighten the picture in the grade to such an extent that the grain was becoming really apparent, plus pushing saturation so much made the colours fizz, and it was the combination of trying to create a strong look and decrease the grain that pushed me to try a massive degrain. Matthew and the producers took one look and loved it. So there we have it. Horrible degrain that none of us like or intended became a creative look. The magenta feel for much of the movie also came out of the need to avoid a blanket warmth that was pushing the film into a tobacco world, so an increase in blue in the shadows forced it into a magenta direction.
