Nicolas Cage's computer generated skull was made from a three dimensional x-ray taken of his actual skull.
Nicolas Cage is an avid fan of the "Marvel" comic, and lobbied furiously to play the part of Ghost Rider.
One of the few "Marvel Comic"-based movies in which Stan Lee did not appear. He had absolutely no involvement in the creation of the original "Ghost Rider." Yet he is credited as executive producer.
According to an interview he gave to the New York Times in 2010, this movie was made during the middle of Wes Bentley's decade-long, extremely serious addiction to cocaine and heroin. He said in that interview that he only accepted any movie roles during that time so that he would have money to buy enough drugs.
