I always look at these superhero films, and I see people hurdling towards at a hundred miles per hour, and then they get up, shake their head, and charge back at a hundred miles per hour. Nobody seems to really get injured or hurt. I don't find any threat in that. There is no tension in that whatsoever.
I like pre-production and post the best. I don't like shooting at all. I find it grueling and tough, but I love post and the whole process of seeing the film finally come together. You start ironing out all the rough spots, and the really bad bits you just throw away. So from day one of post to the last day, you see nothing but improvements.
