This was by far the most roto work I ever did. The problem was that there was no sun and everything had to be roto-ed out. The mountain had to get a surreal look and everything had to be colour corrected: every part of the car, the skin, the hair and the clothes. In order to know if there were no edged or tiny mistakes I used a rather extreme colour correction for guide. That was quite fun because they looked more like smurfs on XTC but it showed us it worked. The scene was a total of 5 minutes, I don’t remember but it was loooong.
