In March, actor Peter Fonda (who starred in Easy Rider) was cast as the villain Mephistopheles. Johnson originally planned to film before an audience at the Docklands Stadium, but instead opted to create a crowd using computer-generated imagery. The director also chose to film in the motorcycle district of Melbourne. By June 2005, principal photography had been completed for Ghost Rider, which was set for a summer 2006 release. In April 2006, the cast and crew performed last-minute reshoots in Vancouver. Character portrayal Instead of a "hard drinking and smoking bad ass" Johnny Blaze, Nicolas Cage decided to give him more depth: "I'm playing him more as someone who... made this deal and he's trying to avoid confronting it, anything he can do to keep it away from him". Cage also explained that Blaze's stunt riding was a form of escape and a way to keep him connected to his deceased father, who taught him to ride. Cage rode a Buell motorcycle for Blaze's stunt cycle, and a heavily customized hardtail chopper named "Grace" which transforms into the "Hell Cycle". The Hell Cycle's wheels, made of pure flames in the comics, were changed to be solid tires covered in flames in order to give the motorcycle more weight onscreen. The film's visual effects supervisor, Kevin Mack, and the visual effects team at Sony Pictures Imageworks handled the difficult task of creating computer-generated fire on a shot-by-shot basis. Ghost Rider's skull flames were designed to become smaller and blue to display any emotion other than rage. Kevin's Team at Imageworks also created computer-generated motorcycles, chains, water, black goo, dementors and buildings. To pull off such effects as the living morph where the hardtail chopper ("Grace") comes alive to become the "Hell Cycle", Sony enlisted teams of animators, models, effects artists, lighters & "Flame" artists. The department supervisors for these teams at Imageworks included Kevin Hudson, Brian Steiner, JD Cowels, Marco Marenghi, Joe Spadaro, Joanie Karnowski, Vincent Serritella & Patrick Witting. Patrick's team bore the brunt of the work as they created the fire using a custom pipeline that automated the set up starting with Maya animated geometry driving Maya Fluids, imported into Houdini and then rendered & composited on top of the live action plates. Patrick and his team set up the fire process and much of the front end automation was set up by Scott Palleiko and Joe Spadaro. The
