Where they tough to pull off?
We had to shoot all of the car chases going no more that 25 MPH because on our first night of shooting a car had a slight mishap and one of our cars slid into sandwich shop window at midnight. No one was seriously hurt. What we had to do was speed up all the chase stuff after that and add digital cars and props where necessary. In some sequences, we created totally digital sections of New York so we could destroy it and when necessary reverse explosions, etc. Mirror world was particularly difficult in this way. It was a tremendously complex task that worked upon the stunt driving of George Ruge’s stunt team driving backgrounds and that were passed off to the talented animators at Asylum VFX (where lots of fully digital shots were added) to pull it off. How many of the effects in The Sorcerer’s Apprentice were CGI and how many were on-set practical effects and which type of effect do you prefer to work with? I love to mix up practical effects with visual effect (usually made from CGI).
