Trivia: Red Dragon
- Enforced Method Acting: Philip Seymour Hoffman was glued to the chair for real, at his own request.
- Fake American: Englishman Ralph Fiennes plays the American Francis Dolarhyde.
- Hey, It's That Guy!:
- The Other Darrin: Everyone at some point.
- Technology Marches On: Dolarhyde chooses his victims through their home movies, which are shot on film and are sent to his company for processing. This plot device was outdated by the mid-80s when the camcorder became a reality. The 2002 adaptation updates the story to Dolarhyde's company compositing shorter home movies into VHS tapes (as the timeframe set by Silence of the Lambs meant the movie had to take place in the mid-80s instead of the late 70s). Of course, that too is wildly outdated. Today Dolarhyde would just stalk victims on Youtube.
- In the television version, made and set in the 2010s, Francis has the option to go digital but prefers film.
- What Could Have Been: According to the Red Dragon commentary, Philip Seymour Hoffman very much wanted to play Dolarhyde.
- Frank Langella recorded a number of lines as the voice of the Great Red Dragon, allowing viewers to hear Dolarhyde's interior monologue/argument, but they were cut.
- Frankie Faison played Barney the orderly in Silence of the Lambs, Red Dragon, and Hannibal. Due to scheduling, he did not become available to appear in Red Dragon until the last minute. Screenwriter Ted Tally has commented that, had he known for sure that Faison would be able to take the part, Barney would have had a bigger role.
