Trivia: Michael Mann originally wanted Francis Dollarhyde to have William Blake's "The Great Red Dragon" tattooed on his back, but discarded the idea after deciding said tattoo trivialized Dollarhyde's personal struggles. When Ralph Fiennes played Dolarhyde in Red Dragon, director Brett Ratner decided to include the tattoo.
Trivia: To get himself into character, Tom Noonan asked that none of the cast members, either people who are after him or whom he is after, be allowed to see him. The first time Noonan met William Petersen is the scene in which Will Graham crashes through the window of Dollarhyde's house. Noonan admits that, because of his request, the atmosphere on set became so tense, people actually became afraid of him. Noonan also asked that those crew members who were allowed to see him refer to him as "Francis."
