No excuses for a dirty lens - shame as the whip-pans/zooms combo is one of my favourite parts of the trailer.
As for the 'BORDERLINE RACISM' joke, we were going to shoot an exchange between the main character and a Nazi soldier, but it was cut because of time - I probably should've changed the voiceover as it's what people always pick up on.
Anyway, thanks for your comments, very helpfull, hope you enjoyed the trailer (and my excuses).
